Look for a shorted wire between one of the left side drive motors and its speed controller. You might be getting voltage on the frame when a motor drives backwards, and another shorted frame connection somewhere (likely a power return or "ground" wire) could be causing your D-Link or cRIO to reset. Or you might have cross-wired motor leads, with one motor connecting to two different speed controllers. That results in very weird symptoms that can sometimes match what you're describing.
You can start troubleshooting electrical issues by removing the circuit breaker from the power branch to one speed controller at a time and seeing if the problem can be narrowed down to one motor's circuitry.
