Narrative:

I was working the san angelo approach position of midland approach control with a developmental. At that time the radar sweep slowed way down (almost stopped). We lost all radios and both primary and secondary radar for 1/2 mins. The only good thing about this occurrence of the problem is that only 1 aircraft was in our airspace at the time. The radar and communications appear to have returned to normal. This has occurred on numerous occasions and to my knowledge no corrective action has been taken. This is an ASR-9 radar.
