If it had a stored code in it the light would come on and stay on. Since it is not OBD2, once you turn the key off and re-start your truck, the code is erased. Sounds like your throttle body may be leaking down causing a flooded situation that clears up once run for a minute. When you turn the truck off, remove the air cleaner and look down into the throttle body (dont move throttle) and see if there is fuel dripping. Could also be a faulty coolant temp sensor for the ECU. Good luck and hope you get it fixed.
