Case TV380 Moves backwards on its own, STOP light lit up

Hi guys,

Today we had our 2013 Case TV380 skid steer randomly stop working on a job. The machine suddenly started moving backwards on its own, and I counteracted by pushing the joysticks forward. As soon as I did that, the machine seemed to error out and the STOP light lit up, as well as the hydraulic override light flashing.

If I raise the lap bar and put it back down, then push the operate button again, the machine does the same thing and tries to go backwards on its own for a split...
