when the engine reaches operating temp and you shut the car off then try to start it back up the engine cranks but does not start the car has a 5.0 H.O does any one know what this could be?

that happened to me waaay back in the day when i was 17 and had my first 5.0 stang. if i remember correctly it was the relay for the ECM getting hot and not working. i think its located under the driver seat, that may be worth checking
 
the fuel pump turns on i replaced the fuel pump a year and a half ago
most of the time when the car will not start i disconnect the #1 spark plug wire from the cap and it fires rite up and then i put the wire back on and it runs fine i put new msd distributor,msd coil.new wire set and still the same thing
 
sounds like a timing issue. to much timing and won't start when it gets hot. does it crank over kind of hard even when it's cold?
 
not all the time when its cold it fires rite up the car is a speed denity car i still need to convert it to mass air but i need a wire harness and ecm from a 91 mustang 5.0 H.O
