Well I found the problem. One badly damaged spark plug. The picture shows major arcing damage on the terminal connector. The question is how and why that happened.

- 114K miles - Second owner. 42k mile from me.
- Likely water damage from power washing.
- loose spark plug wire

All three factors played a role on this plug.


Car runs like a champ now. Maga power increase and no more cutting out or misfire after 4500 RPM. Took it to Red line and she kept pulling hard.

Conclusion:
I had two major issues going on at once.
Bad CPS and bad spark plug.

Solution:
Fantastic forum help.

Thanks folks!
