On the radio front, should be quite easy to resolve, its either the radio itself (internal fault) or loom problem, could also be a lose fuse.

First I would swap the fuse, second whip the radio out and see if any of the connectors are loose.

Previous owner could have had a handsfree kit he has removed, and disturbed some of the wiring (friend had an RS6 with intermittent front speaker, turned out due to the above) if no joy then whack a multimeter on the supply pins and have a drive around see if it drops out should be 12.5-14.4vdc

I would suspect the radio though, which one have you got? Also when it comes back on does it resume what it was doing or is it reset?

hope the above helps!
