wow, alot has been going on since i went to work today. lots of reading to catch up. at this point yuo really need a scan tool that can read live data and you need to get a live fuel pressure reading when the truck is acting up. its weird that you can go 30 seconds or 30 minutes between problems.

i really did not read this thread all to well so i dont know if you checked this.
if i was in your boots i would pull off both valve covers and check the wireing harnes's. they may look good from the top side but could be fried on the other side.
just my .02 cents.

and from reading your Sig, it sounds like your making your own fuel. could you have made a bad batch? another thing to think about.
but id still say pull off your valve covers and check out dem der wires

I will pull valve covers.
New info:
Really hard to open fuel filter. When I do air blasts out and feels like it is building lots of pressure. Could this be a problem and lead to mine?
I don't make my own fuel. It is waste veggie and i have changed all the filters.
Should I get a new schrader valve?
I am on my way to get the scan tool. But no CEL. Will codes show up?

So, got a scantool from O'reilly's and it says CEL is ON, (yet I don't see one on the dash), and it says there are no codes.
Truck won't start right now. charging batteries from the cranking.

Coon, which regulator do you mean? IPR? How do I pull this. I ended up pulling a oil line thinking that was it. I guess it is on the firewall side of the HPOP and under the fuel bowl?
how do I get to it?

Now the tach doesn't move at times. I am thinking about pulling and replacing the cps? What could cause a cps to go bad so quick?
I switched from synth oil to petro based. Last oil analysis said I had a high lead content.

does this scan tool give live data or will it just pull codes?
if the tach isnt moving you have wiring or a bad cps, sometimes you just get a junk one.
the reg i spoke of was the fuel regulator on top the fuel filter housing.
was the truck running and died or has it been sitting. what is the scenario fo rthis nostart?

The truck ran for about 30 min or so and quit. Has been sitting for an hour. cranks and cranks and got jumper cables on one batt and trickle charger on the other.

first off, how long did it sit after it died befiore restart?
second , let it run another 30 minutes and see if it dies again.
if so then we'll check the ipr. its not too bad, first timer...maybee an hour? the trick is gettting your big hands into that little space. its just 1 connector, i 3/4 nut. then the whole back falls off of it. then a 1 1/8 wrenc(i beleive) is used to lossen the regulator and it just unscrews.
some find it easier to remove your fuel pressure regulator to get more room.
