Wow, not sure I would buy all of this at once.

So, assuming you have not cleared any codes yet, suggest you get Freeze Frame data and post it back here.

The clear codes and drive car and see what happens. Assume the car is drivable?

The when CEL comes back on, immediately check codes and Freeze Frame data and document.

This almost sounds like a grounding/electrical problem on the surface??
