1961 no power after start, engine dies

[Mrjagrock]

Just rebuilt and added Edelbrock Heads, Cam and Sanderson Headers. Probably more cam than I would like but the real problem is after running a few minutes, all electric goes off and engine dies?? Seems to be tied to Starter solenoid, but not sure. Ideas anyone?
Thanks.

Check your ground on the engine block. Sounds like it's loose.

Sounds like circuit breaker that feeds ignition. They reset after about 30 seconds or less and everything should work momentarily.

How about running a hot wire from the battery to the positive side of coil. If it stays running you know you have a wire to coil Problem. You could have a bad coil. It run normally until it heats up.

Believe it or not, it was the Solenoid that I had just replaced with a cheaper one earlier that month!
