With this particular mount the power connector is unfortunately flimsy and causes voltage drops and communication issues. I replaced the connector with a screw secured one and didn't have these issues after that.

This is exactly what happened to me because of a noisy power supply (and it was a 12V 5A one, so no low current issues, just noise). Looking at the logs it was clear that DEC and RA counts were off-limits (meaning off the expected number range) because of spurious bytes being received.

I would be very wary of just disabling the "abort tracking" option as a permanent fix. Communication problems also affect slews and you might end up with your scope trying to become one with the tripod.
