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!

Even though the engine will not turn over just makes a clicking noise

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!

Very true my bad, i changed the starter out on it so its not that.
