I wouldn't be too concerned with the contribution tests at this point. Afew other things come to mind-
-yes, it is normally much easier to diagnose a truck when it's in it's factory settings, but in your case, that would add expense that might be able to be avoided.
- first thing to do is make sure the regular maintenance is up to date-ie oil change/filter, fuel filter, air filter
- You have somewhat limited info on everything that is happening, but with what you have it almost sounds like a fuel issue, which isn't monitored by the PCM. Other indicators would be some white smoke coming from the tailpipe as it's stalling. Possible causes are a faulty fuel pressure regulator, fuel pump, plugged pick-up screens, plugged filter, faulty o-rings in the water separator ...I would get a fuel pressure gauge hooked up to the end of the fuel rail (1/8" NPT fitting and a 0-100psi gauge) and tape it to the outside of the windshield. You want to check it under heavy load, not just idling. You should have about 60psi, but that might vary a little. If it's dropping to 15psi, it's a problem.
