Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Runs well when i first drive and after driving it for over 30 minutes or so when i come to a complete stop it shuts down. Also after the truck has been running for over an hour and i turn the truck off it will not start back up untill it cools off. Any ideas of what it could be ?

When it will NOT start is when a mechanic needs to test for correct fuel pressure and ignition fire!
Well if you had posted it will not CRANK instead of will not START , i may have known the engine isn't turning over! Big difference,, however at that time is when a mechanic needs to test it to see if its the starter or a circuit problem.... guessing does no good!
