Sounds like the serpentine belt is getting wet and slipping. Check for missing or damaged splash guards on the passenger's side near the wheel. Also, if the serpentine belt is old replace it. HTH. -Jim

Sounds even more like a failing alternator. Check the belt as suggested above and have the alternator tested. It probably won't leave you stranded, the battery is there as your backup, but at some point it will stop charging altogether and then your battery will slowly go dead.
