I had a problem for a few weeks where my truck would just die while driving. I would pull over, wait 5 minutes and it would start and be fine for awhile.
I took it to Ford and they cleaned throttle body and maf sensor. It didn't fix it. The problem got worse. I took it back and they found the inertia switch wiring to be the problem. The wires going to the switch were almost burned in two and the switch itself was burned at it's connector.
I paid $143 and am very happy now. NO more stops!
