Robot lose power when reverse directions?

I just read these 2 threads

The problem is that anytime we reverse directions, say we are going fast and we go reverse to stop the bot, we loose connection with the robot. When this happens, all the electronics loose power for like a millisecond but the CRIO retains it's data as in the RAM doesnt clear.

Our setup is 4 Victors each connected to a CIM, we have the 2 left victors going to one port on the sidecar and the 2 right going to another port on the sidecar. we use the "Cable, Servo, Y-splitter" PWM cables. Our radio is wired directly to the 5V Wago connector on our PD board but we had the same problem with the 12V to 5V converter.
Our electronics only comprise of Crio, PD Board, Sidecar, Radio, 4 victors and 4 cims.

So does anyone have any ideas? We are pretty sure that its not wiring because we checked like 10 times. One of the threads said it had to do with electrical arcs in the motors when we switch directions or some spring in the DAP. Is it possible to check if its a Crio reset or a Radio reset? Also, is there a way to check to see if the entire board really is going out?
