This issue continues to plague me. Fuel filters were clean but for a few bits. I had been running an EFI high-pressure pump regulated way down to 4-6psi and just swapped to a carb specific pump. No effect.

Running out of ideas! I guess I can replace the ground straps which all look perfectly fine. It's so frustrating as it runs amazingly and pulls like crazy... until it falls on its face. It's got to be electrical...

Do you have the original HEI that you can pull parts from?
Coils can do funny things when they get hot, like cut out.
Could be your coil is overtaxed or weak in some way and it gets overheated briefly. Electrically not physically. So it gets a brief break then is good to go for another short period. Turning the key off would de-energize the coil so maybe....?
Is the ground strap you added of decent size?

Another electronic component that can get hot is the module.
Last one is the pickup coil under the cap.

It's kinda acting like a car with a crankshaft sensor would if that sensor were going out. A crankshaft sensor is just a pick up coil.

I'd try swapping one then the other if you got the parts or maybe even buy them if you don't figure something else out.
