Possible FMS problems.

[Canon reeves]

Our team competed at the Arkansas Regional and we ran practice matches all Thursday, no problems at all. There was no score keeping during these matches and we did good. During our first qualification match we ran great until the last 15 seconds we lost power to the C-Rio, and all Comm. and Code. During the next match our battery fell out. And in every other qualification match we would run, then our C-Rio would reboot. Sometimes it would happen when we took hard hits, others we would just drive forward and then reboot. So first we replaced the C-Rio, same problem, all of the wiring was fine, had multiple inspectors confirm that, Then we replaced the PD board, took it to the practice field and it worked fine, we ran at full speed into the low goal multiple times, it was just fine. Then we went onto the field on saturday and same problem happened. We replaced the main breaker, same problem. So then we got picked for elims. and during the time in-between our match, we ran on the practice field with our alliance members at least 20 minutes, just fine. We went out on the field, drove a little bit, and re booted. same thing happened next match. Any ideas what could be the problem?
