Here are two likely solutions:

If you are using firmware 2.02, upgrade to 2.03beta3. The difference is that 2.02 doesn't apply tool offsets in the tpost file. Also, in tpost3.g, do a small X or Y move near the start, which should cause the Z coordinate to be corrected for tool offset at the same time.

In tpost3.g use G91 then G1 Z5 (for example) to raise the head 5mm. The head position will be restored automatically before it resumes the print.

@phaedrux you're a great help, I really appreciate it.
The probe ran without issue for 10 minutes before I called it. I decided to try again while moving the x axis back and forth and at almost the exact same point it failed to probe. The little blue light dimmed slightly.

I swapped in the true probe, and repeated the test and it happened again, almost the exact same spot.
With your help I'm convinced it has to be wiring related. Tomorrow it's going to get a new wiring harness that's 2 meters without any extensions
