Xeno,
What you describe is a classic failure mode when a wire is shorted to chassis and the Crio is not isolated from the robot frame. When the motors are driven on the left side (to turn right), the resulting voltage differential either pulls the Crio power supply below operating level or disables the Crio power supply in the PD. While a video would be of help, please try describe the actual fault and how long it lasts. Does the robot stop functioning for 10 seconds, 20, 50, etc? Are you tethered or operating wireless? Do the controllers show disabled or full throttle? What does the battery voltage on your dashboard do during the failure?
