Thinking I was having an issue with the new probe I replaced it with a clone BLTouch that performed the same way then again with a second clone that had identical behavior. That's 4 probes all with the same behavior. I could use a BLTouch guru to let me know what that failure type means and how I should troubleshoot from here.

I have checked the wiring closely and there are no visual problems that I can see.
