I have this problem to where if i drive my stang for about 20 to 30 minutes , turn it off and try to turn it back on it wont start. It will try as if the battery is going dead. If I wait for 20 minutes or so it will turn back on as if nothing every happened. I have replaced the battery, starter, and alternator and still no luck. Any help???

It usually turns out to be heat from the engine affecting the starter, especially if it starts OK after sitting for a while, but cranks slow when hot, also check to make sure the engine isnt running too hot, and check base timing by unplugging the spout connector and checking the timing with a timing light.
Engines will crank slow if timing is too far advanced, and it will ping or knock under load! Battery and cables can be a problem too...Check for voltage drop at cables, especially the negative cable.
