We suffered with this more than I like to admit last year.
First off, make sure the 12v to 5v converter is properly connected to the +12v out from the PDB. Not just a breaker, but the +12v dedicated for that purpose.
Next, and this is what turned out to be our whole issue, make sure every connection in the wiring between the PDB and converter are solid as well as the output from the converter to the radio power plug. We had not one, but four, pour soldered connections. Once we found those and made them right, we had no more issues.

Watch the radio next time it fails, if it is rebooting, you can be sure the issue is on the power side. Additionally, if you gain control again after about 45 seconds, that also indicates a radio reset.
