I agree. I have seen this exact behavior in our '04 robot when the main battery is low. (It is actually rather hazardous) What happens is that under a heavy load the voltage they main battery supplies drops, and since the robot controller needs ~7V to function it turns off. Since the Victors are no longer receiving a signal, the default to neutral. This stops the motors drain on the main battery, allowing the voltage to come back up, which then allows the controller to reboot. The pause is caused by the time it takes to reinitialize the robot controller. The robot then reinitializes and the motors start moving it, closely followed by them pulling the voltage down and reseting the robot controller again. The reason this wouldn't be present during testing on blocks is that the motors aren't under significant load. Try installing the backup battery, or charging it if it is installed and see if that clears up the issue.
