I am going to repeat what Mr. Aubry and Mr. Mac said. Last year team 47 had this issue for the entire 1st competition. We could not figure out what was going on and the robot would just turn off about 20 to 30 seconds into the match. We were in 2nd gear on the drive motors and we were kicking out the breakers the entire time. We moved to first gear for the next competition and had no problems what so ever and so we stayed in first all season. This year as far as I know team 47 tried 2nd gear agian and it did the same thing so they moved to first and I guess it was better, but I don't know if they stayed in first or not. Just try switching to 1st gear if you are in 2nd and see what happens. There is a trade-off though, you will lose speed but it will be tougher to push you around and your machine may run flawlessly.
