What are the temps in your shop? Just for fun, leave the control box door open and place a fan blowing directly into the box. Possibly a bad solder spot that opens up when warm or other component.

It is late June in Texas, so it on the hot side. Too late for that test. Already pulled the boards. While I understand the suggestion, I have a hard time wrapping my head around a break being the culprit. The behavior seems more like a short that allows Z signals to get to the Y motor. But I'll never claim to be an electronics guy.
Follow Up: Apparently there is a problem on the control board. Installed a new control board and the problem disappeared.
Thanks for the update. Glad you got it sorted out
