Need help diagnosing this bizzare radio failure

The CDR220 on my '99 cuts out, as in loses all power, at random. Sometimes it will cut out for just a few seconds before turning back on, sometimes it won't work for several days. It seems like electrical loads sometimes influence the unit losing power, such as turning the AC on, using a window switch, etc. Another time I noticed that the radio would work just fine with the engine idling, but lose power once you gave the car any revs! What's interesting is it works 100% of the time when the key is turned to the accessory position, but once you start the motor, the intermittent failures start. Car has no other electrical glitches.

Ignition switch? Bad head unit? Fuse? What's the prognosis?
