Truck runs like a champ first 5 to 10 mins then gas pedal drops out, no power, if you try to give more fuel it stalls. You have to wait a few minutes to restart or it just cranks. If you do wait it will restart and run for another few minutes and the same thing all over again. Will stall out sometimes without trying to give more fuel. Truck has new fuel tank, pump, fuel lines, fuel filter, and new PMD. Pulling my hair out trying figure why since I have not been able to find anyone that can give any kind of answer. Including my mechanic.
