ok. here we go. my 1999 5.2 pickup wont start unless i unplug batt and tps. let it sit for min, and then starts right up,runs fine after about a min it just shuts down. wont start back up.it will not start without doing this . runs nice for a min[X(]

 

i once had a lincoln town car that had a problem very similar to that. It was a shorted out computer, maybe try picking one up at a junk yard. Good Luck
