Have you checked your backup battery? We've seen very similar problems, but it traced back to a undercharged backup battery---as the drive train started to draw full current (4 CIMs pull a lot of current), the main power bus would drop low enough to cause the bot to reset, which if you are in autonomous mode can cause some very weird behavior. (It took a while to debug, since the bot ran perfectly if put up on blocks (motors freely spinning), only showing up when we put it down for real tests).

A fresh backup battery solved the problem for us.
