1969 charger help

[craftvinyl]

I am having a terrible electrical issue with a 69 charger (440)

changed it over to a one wire alternator, the car will start, run for about 2 minutes and the just quit, almost like someone cut the key off, then the car won't start back up until it has set for a few days

No issues before the change? Installed the one wire alternator and this issue started immediately following the installation?

[440]

Won't start for days sounds interesting. I'm guessing it still cranks, just wont fire?

If it won't start for days, you're better off than the poor bastards whose car shuts off and restarts immediately.

IOW, you have plenty of time to do basic troubleshooting 101.
