when i turn the key in the ignition it hesitate to start, then once it start it has a hard time continuing running. after driving for 15 minutes or longer and it sit in one place it will shut off or it u turn it off after driving longer than 15 min it has to sit 45 minutes to an hour before it cranks up again.Why is that?

Check the coolant temperature sensor, idle air control and EGR/PCV valves and throttle position sensor-also clean throttle body-
