I owned a 94 GT for a few years. A few weeks after buying her she started randomly stalling, running rough and loosing power. Eventually after driving her for anything longr than 20-30 min if I stopped and shut her off for any period of time she would not start again for at least a day. after checking, testing and even going as far as throwing another distributor at her ( witch solved the issue for about a week) I narrowed it down to the HEI module thats located inside the dizzy due to the design of the engine bay and the location of the dizzy the heat generated under there cooks the module causing it to fail over time , my choices were….1, replace the module constantly. 2, install an external module. 3, install an external coil and dizzy cap. my solution was to run a jumper wire from my fuel pump relay to the module power wire allowing it to stay powered up as long as the fuel pump stayed powered up. it was supposed to be a temp fix but i ended up driving it like that for about 4 years without issue.
