If the truck starts and dies RIGHT AWAY...and does this ALL the time...it could be the theft deterrent system needs to be reset. Happened to me in the middle of Oklahoma. Sounds like exactly what my truck was doing.
I had inadvertently activated the theft system by reaching in the window and opening the door... Whatever...It took me by surprise and I ended up bringing it to a dealer(tow truck for the yankee) and they hooked up tech2000 and fixed the problem for free
Indicator was that the "theft" light on the dash would come on with the key in the run position and not go out.
The truck would fire, run for maybe 1-2 seconds and shut down just like you turned off the key.
There is a procedure of key manipulations that will clear this out but I do not remember what it is.
If your symptoms are similar then it might be worth a shot.
Good luck!
