Hi, new to the forum I have a 1966 Dodge Charger that has a 440 big block when I start and run it for a while then cut it off I can’t get it restarted and the coil has no spark so I changed the coil started it let it run cut it off and it’s doing the same thing I don’t think it’s the carb it’s new so I think it’s an electrical issue somewhere any help would be great so frustrating thanks

 

Use a test light and see if you are loosing power to the coil when this happens? If thats is the case, Check the power at the ignition switch for the same.
