There is absolutely no reason to reimage the cRIO in this circumstance. It is a complete waste of time. And I didn't look too closely at your code, but I doubt that is the issue.

1. Verify that your battery is charged. As the motors draw current, the voltage of the battery drops. If it drops too low, the motor controllers may stop working.
2. Verify that the motors are not fighting one another and that they are not drawing too much current because of binding or because of the gear ratio.
