Question about 2003 Ford E250
Four things you need to have combustion - Spark, Air, Fuel, and TIMING. I would look into the crank position sensor wiring. This would effect the timing. Then no matter how much spark and fuel you have, it will not start. If the crank position sensor goes out, it will die while you are driving it, but it that sensor goes bad it will not start back up. But if there is a back connection in the wiring especailly on the ground side, the the resistance will build up when the vehicle get hot. Which could cause it to make it seem like a fault has occured in CKP sensor. A scanner might catch a code for this. A good scanner that can graph will be the real way to go to know for sure.
