I had an older Ford that would do that. At first it seemed like a ground issue. I replaced the ground wire and also the negative battery lead. Worked for a while but then after driving it then turning it off it would not start. Turned out I had a bad fuel pressure regulator. Fuel pressure was so high it would flood the engine after I turned off the engine. If I waited a few hours it would fire right up. Check your fuel pressure with a gauge to a schreader valve on the fuel rail.
