I had a problem like this with a Ford my dad bought at auction. The first thing to do is determine if it is fuel or electrical. Most the time it is electrical, you can do this by rigging a light up to the coil, when it has power the light illuminates. Drive your car, if the light goes, your car dies, you know it is electrical, and I would just take a wild guess here, did you check the ignition switch? If everything else seems fine check the switch! Just think of how many times that switch has turned off and on that engine! Good luck!
