After driving 30 plus minutes my truck stalls out when coming to a stop sign or light. I can restart the truck but after a few restarts the engine kicks knocks and completely shuts off. It will restart about an hour later but the same cycle begins.

Good afternoon,

I would check the fuel pressure during the time it will not start to see if the fuel pump is working.

Fuel Pressure Specifications:

Engine running or key on .................... 64 +/- 8 psi

Engine off .................... 64 +/- 8 psi

I would also check for spark as well. Make sure it has spark while cranking.

If you have any starter fluid, try spraying it into the air filter and see if it starts and stalls.
