If you are doing this, make sure your motors aren't fighting each other in the gearbox. Be absolutely sure when you do this that the two motor controllers controlling the motors in one gearbox are flashing the same color light. If you have motors working against one another, it can trip the overcurrent protection in the controllers and have symptoms of what you are describing.
