1984 Mustang GT 350 electrical
 

My 1984 Mustang GT 350 will start and drive but can go dead at anytime but will start right back up. It may do it several times but also sometimes it will be a few miles before it does it again. I have a new battery, new voltage regulator, good solenoid, so I am at a loss as to what is causing this. Any ideas ?

cfi or carburated??

4 bbl carburated.

could be the pickup/stator inside the distributor or common was the duraspark box
