bad misfire and ignition problem.

You may have somehow developed reverse polarity in the distributor pickup circuit. AKA if you reverse the two pickup wires, this changes the timing relative to where the rotor is pointing to the cap contacts. This has become known as "rotor phasing." You can search that phrase, there are all kinds of videos, etc talking about that.

Your fancy pushbutton (and why did you do that) may cause a DIFFERENT problem
Once I am at the car again I will take pics and go in detail how the push button is wired. We did it because we figured out the key issue but we just liked the push button and re-wired everything on the ignition coming into the car from the bulkhead. I am very convinced the push button is wired correctly, because we had good charging, no fires, no misfires, nothing was wrong… until today after the shop messed with it.
