One common problem (that we had last year) which can lead to temporary power loss long enough to restart your radio is the main breaker. From what I've heard, there are a few every year that have this issue.
Try tapping your finger on the red button on the breaker, (the one you would use to power off your robot) if it causes your robot to power cycle, that's your issue - at least one of them.
