Ok, just got back from the first test drive, the fuel pressure may be the culprit as it did it again, let it set idle for a minute, was able to drive a few more miles until it started bad again, And yes there were some bubbles on the oil dipstick. I'm leaving my laptop here on my work bench running, i'll refresh the page every so often to check back as I drop the tank and follow Kwikkordead's suggestions.
Any input from anyone is appreciated

Of course, you also mentioned that the oil has less than 100 miles on it. What oil did you put in your truck?

grrr, i've i'd have known about this earlier, i'd have posted it. The guy I bought this truck from just called me back, I'd left a message asking if he'd had any problems with the truck. This is what I learned from him. 1 The "NEW" injectors he purchased from some company in florida while down there, and had them installed there, they are REBUILT injectors, not new. 2. He had been burning Veggie oil (both new and used) mixed with gas, but not on the replaced injectors.
I'm in Alabama, so cold temps are not an issue... but i've heard there needs to be a pre-heater mod or similar to run veggie oil etc, or some other mod.
So, now i'm not so comfortable with thinking its not injectors either.
If this was a D-9 Dozer, or a Komatsu PC400 track-hoe or even a W900 dump truck with a C-15, i'd have had it done long ago, BUT i've noticed ford diesels are a critter all thier own! and can be VERY nitpicky about how everything is done on them.
THANK YOU ALL in advance for the great help!

Delo 400 SAE 15w-40 LE (low emission) And yes, I can see how that would effect the fuel pressure. I checked it about 5 times in a row, about 10 or so small bubbles on the dipstick each time. I have a couple of people here helping me ( my workers from the shop i'm forman at) dropping the fuel tank as we speak, I may go ahead and check that out too while they are doing the tank, kind of kill two birds with one stone

That sucks if it's Pensacola Diesel injectors in there. They have the worst reputation ever for rebuilding PSD injectors.

Sorry to be a post hog, and keep posting before answers are given,but I have a question. I have a Cornwell Scan tool exactly like the one pictured below, (by OTC) upgradeable for specific trucks etc. If I cannot get it upgraded to run a Buzz test, is there anyway to run a "self" buzz test on the injectors? and what exactly do I need to listen for, and how long should they buzz? I'm gonna have to buy a few rounds by the time this truck is running right

I don't know if that scanner will buzz test the injectors, but you can overfill the crankcase, submerging the oil pickup tube.
If the engine shows a sudden improvement, you've found your problem.
You'll still see a lot of bubbles in the oil because the crank is going to be stirring the oil, but it still should improve the way the engine runs.
If there is no change at all, then you can be pretty certain of the fuel pickup.

I don't know if its related or not. I was checking a few things since i've found out he ran veggie oil in it previously, I pulled the fuel filter (I had one of my guys replace it for me the other day while I was doing other things) and the first thing I noticed is how cruded up it is inside. Also, doesn't the black disk shaped thing or tube (verticle) supposed to be spring loaded, or something like that? Seems like I remeber some part of the filter houseing being spring loaded , this one barely moves at all, no springy action at all inside or on cap filter housing.
Here are a couple of pictures to show the inside of it. Thanks once again!

Update
I think i've scared everyone away from this thread! 
Anyway, the fuel filter housing has tons of crap in it, and does not drain hardly at all. I've been cleaning it out, but when I refill it halfway to flush it some more, it takes 30 mins prolly to drain out, i'm assuming its from trash that's gotten into the line etc. Questions I have, Where does the fuel drain to, and is it possible that all this trash could have gotten to the injectors? The "output" fuel line has a hard black scale inside of it also. The pictures really don't let you see the full INCH of trash in the very bottom.

Those pictures are a very good illustration of why I don't bother with veggie oil fuel.
I can earn more money in the time that it takes to pay for a tank of fuel than to deal with all the lost time dealing with issues like this.
But I digress................
.
That appears to be the fuel bowl heater, but it looks a lot different than mine.
Mine must be the older style with the single exposed wire on a plate.
And judging from the looks of your fuel bowl I would be pulling it out of the truck and hot tanking it.
It also makes me pretty sure that your fuel tank isn't in much better shape and that your fuel pickup screen is seriously clogged.
Curtis has a good point about the airated oil, but I wouldn't bother chasing that right now until the fuel supply is cleaned up and verified 100% operational.

That's what we're doing as we speak, dropping the fuel tank, And I'm glad I sent to the local ford dealership before they closed for a complete fuel line kit, i'm just going to go ahead and replace all the lines, just to be sure. I'm pulling the filter housing and going to clean all that also.
I did notice that when I was trying to flush the housing, I had someone turn the switch on for me to pump more fuel into the housing. The fuel surged into the housing, stopped, surged again and did that 2 more times before I had him turn the switch off. Is that normal? The pump made a very audible buzzing sound when pumping, stopped, started etc... almost like it bogged down. ????

The pump is drawing air into the fuel stream through the quick connects between the fuel tank and the pump inlet.
There are two ways of dealing with that.
One way is to get rid of the Ford connectors and just use fuel injection rated fuel line and standard screw clamps..
The absolute best solution requires a bit of work, but in your line of work it should be a cake walk.
What you want to do is to migrate the fuel pump to the end of the fuel pickup in the tank.
I did that for my truck and the difference is like night and day.
The fuel pump that I used is not a standard Ford pump, it is a Bosch pump part number 69 430

Wow, I'm amazed after reading the other posts and seeing the pictures. I've never seen a fuel bowl look that dirty before. You've got a lot of problems now, and I think you will continue to have problems down the road. That fuel system is really messed up.
I think your truck is a prime example of what happens when someone runs straight veggie oil and does it improperly. Definately can't just throw veggie oil and gas into the tank and hope for the best. I wonder if the previous owner fell for the Diesel Secret Energy scam? Basically, that's what will happen if you run veggie oil and DSE without a conversion kit.
