It sounds like the CSA was on to something - a radio reboot typically takes between 30 and 40 seconds to come back (the DS logs tell you exactly how long your robot was down). In contrast, a roboRIO will take around 25 seconds to reboot.
Common causes of radio reboots:
- Brownouts due to your battery being low. These events correlate to large current draws
- PDP Fuses. Push them in all the way
- Multiple things plugged into the radio source on the VRM
- The barrel connector not being plugging in all the way, especially if it's an older one
