I'd check my battery cable and all the grounds. Just follow any wire coming from the battery, and see where it goes. Check grounds as well.
Keep a 10mm socket or wrench with you too. If anything is loose, it's more than likely a 10mm bolt. That car has 100's of them. Check your main fuse box, too. Check everything. lol

If you're lucky enough to have an Autozone, I'd take the car there and have them check the battery for you. It's free. I've never had this problem with a Honda, but I've had it on my 67 Camaro. Battery seemed good, but everything would reset for no reason.
