Dad drove the truck home from the dealer and on a few errands. He mentioned that the power seemed more consistant than in the recent past. He said they did do cleaning on the vanes, but we should know soon, because next weekend we are going to be heading further north to go camping. We will see how well the truck does pulling the 5th wheel!
I say he should just let me take it to the drag strip and blow out some carbon!!!!!!!!!!!!!LOL!

If the truck instantly dies out driving, sometimes it could even just be momentarily, replace the crank sensor. it's on the front of the block on the right hand side, one bolt and an o-ring hold it in, 50 bucks at your local ford dealer. we have 2 wreckers and a ramp with a 7.3 and they've all done it, all at the most excellent of times. I'm sure it's the same problem, it sounds like it at least. put a graphing meter to the sensor and if it's the slightest bit fuzzy she's junk. oil wouldn't cause the stall unless it was leaking severly and dropped below 8 or 9 quarts, but it wouldn't start back up after time, at least without adding oil. when it stalls cycle the key 3 or 4 times before you try to crank it again and if it seems a little more willing to turn over you've got a fuel problem. there's an in-tank pump, lift pump/water separator inside the left rail @ the drivers door, a driver pump (which is the main pressure pump) @ the fuel filter housing, and an injector pump somewhere over the intake. you need something like 500lbs of fuel pressure to start and the tac should jump to 150-200rpms. try the sensor, i'll check back, i guarantee that's it.
