Main relay? Thanks, I'll keep it in mind.

The only other things I can think of is the clock will flash off when the radio does, and occasionally the clock will lose time after being parked. Yeah, I guess you could say I'm losing complete power at times. It's my wife's car, so I'm pretty interested in getting it fixed asap. I took it to Honda, but of course the problem would not show up. I stood there in the shop while we tried to replicate the problem, but to no avail. When I left it happened twice before I got off the lot. It's looking like 99% of the time it happens only when rolling. Possible loose ground? Connections to the underhood fuse panel are tight. I had gone out earlier and unplugged the relays and replugged in case some corrosion had built up, but connections looked good.
