The field control system cannot cycle your robot’s power or tell it to run autonomous again.
You're correct that the field control system cannot cause a robot to re-enter autonomous. The field control system is only able to turn the robot's transmitter on and off, nothing else. Autonomous is controlled by a timer running inside the robot. Therefore, if the VEX microcontroller resets for any reason (too much current being drawn by the motors and buggy code are two common causes of the microcontroller resetting), the robot will restart its autonomous program. As hard as this is for the teams to accept, this is not the fault of anything external to their robot.
