Turned out to be a bad Thunderbolt 4 ignition module. Replaced it and not a problem since. I did stick with the Thunderbolt stuff cause I bought all new wires, coils,and pick ups in distribs. Works great now.
Are you using the v6 module and what kind of timing are you running.

Im using the V8-24 modules right now. But I do have a set of v6 modules I will be using in the future. I would recommend them, they advance quicker. 34 degrees total advance.
