Default '78 mach 1 5.0 302 V8 Hesitating, stalling

My baby was running perfectly. Then she wasn't, overnight. Went and started her up, gave her the ol warm up and took off. Didnt make it very far. She hesitated, sputtered, stalled. RPMs just drop off a cliff. I've replaced the distributer cap, plugs, wires, etc and fuel pump seems to be fine. There has been about 6 of us completely stumped. Maybe someone has an idea? I'm a plug short of doing a make it run dance!

Replace your Dura Spark Ignition box. Bet you have a blue spark at your coil wire when you check it.
