Audi Concert Randomly turning off
 

I'm experiencing an electrical demon...
Every so often the radio will go dead intermittently at random intervals.

I have noticed though that it seems to happen mostly on hot days (like today).
Today for about 10 minutes after I had gotten on my way it would turn off then on then off then on for about 3 seconds each time. after the AC had been on for a while it seemed to not do it anymore.
has anyone else run into this situation?
