I have a stock 89 mustang 5.0 , the car starts up great when it's cold but when its running for 30min or so and the motor starts to warm up and if I turn the car off it will not start again it will just keep cranking , until the motor geats cool again . It has new spark plugs an wire's I changed the distributor , new coil and the car still dose it . I don't know what else to do so if anyone could point me in a good direction it sure would be greatly appreciated cause I'm totally lost thanx guys

Does it start hot with the accelerator pedal held firmly to the floor?

the car has a new coil, I ran the car for 30min then turn the car off and tryed starting the car back up but would not start just cranking over at this time I checked for spark so I took off a spark wire and put a extra plug I had laying around in the spark plug wire and put it next to the shock tower and cranked the motor over , and their was spark
