Rep Power: 0

While driving my 2002 Honda Civic EX, the stereo, and possibly other electronics, i am still trying to watch for it, randomly shut off and then turn back on a couple seconds later. I automatically notice the radio, but by the time i realize it has lost power it is already back on. It almost is like i feel a small jolt or something if the car is not moving (ie at a stop light) and then it does it. Could it possibly be a slipping belt? I also have had some belt squeaking issues. Anyone have any good ideas? I just made sure the power cables from the battery are tight. Thanks!
