well do yourself a favor and buy a manual. start by picking up a code scanner or get it scanned at a shop. if there are no trouble codes, more than likely it is the TFI module on the distributor.

Thick Film Ignition system used on 5.0 mustangs tend to overheat and go bad. So once the car is warm, it will begin to lose connection and cut-out, not allowing the car to restart untill it has cooled down.

The 95 has the module mounted on the pass side fender apron.

when it won't start check for spark or fuel, all you need to narrow it down to a system is an old spark plug and starting fluid
