After the testing when the robot drove forward and shut off, we tried turning it back on, it took a few times but after it did turn back on we had no connection whatsoever, we tried rebooting, reset the radio, re-deployed code, exited the driver station then came back in. Under the diagnostic page on the driver station there was no light for the bridge, but there was a red light beside "robot". I've been trying to get it to shut off by shaking and dropping, and it still isn't rebooting like it is when I drive it. Is there anything else in the driver station we can use to diagnose the problem? Thank you guys so much, the team really appreciate's your help and GP!

Are you using any of the DIO connectors? I have seen instances where the +5V wire from the PWM cable will short intermittently to ground. This is normally seen when the White and Black wires are used for a Limit switch. The RED wire is cut and left hanging instead of being cut back and taped. The end of the wire will come in contact with the Black wire causing the 5VDC in the Digital Sidecar to turn off.
