One of your batteries is on it's way to Vegas. Did you load test them indevidually? (not in series)

I have had this happen before, and currently it is happening again. Indevidual load test shows that the passenger battery is really.....really weak.

Well, with only 57K, I would not think that the LPOP would be going out already...but I've seen stranger things happen. I doubt it's the problem, but I wouldn't completely rule it out just yet. Symptoms are what happens when the LPOP is beginning to fail. I'd just test it, so you can rule it out. Get a mechanical gauge, install it where the oil pressure sensor is now (top of the HPOP res), and watch it while an assistant cranks. Do this before the first start of a day, when the truck typically has trouble starting. Watch the pressure, and if it takes some time to build, then suddenly fires, you may have found your problem.

Before you do that though, you can remove the sensor and look down in the resivoir before first start to be sure it is full of oil.

If you didn't do it already, try what Dan suggested, and load test the batteries individually.

Trash in bottom of tank (now in fuel filter) or air in the lines (should work itsself out) maybe.

If tach is dropping suddenly when it "misses" kinda points back to CPS'ish issue

Good the starting issue is worked out. I'd say air in the lines is causing the shaking. It can take some time to work it's way out. Give it 100-200 miles.

I cant prove it but after getting up close and personnal trying to learn the electrics of the powerstroke I believe that other than just a weak battery draining the good one a short at the cell level of one battery can cause a ground loop and really cause havoc with the computer control systems. A cell level short can be very hard to find and diagnose as sometimes the only indication being a slight drop in amperage output depending on the health of the other cells.

Did changing the batteries finally solve your problem?

Was the stalling you experienced simply running low on fuel? Did this correct itself with time?
