Often it's an alternator diode. Check the battery first. When batteries start to go bad they can often start to discharge over a couple hours. Take it to an auto parts retailer and have them test the battery and alternator for you. I had the same problem with my '92 Windom (ES 300). It was a faulty trunk mounted CD changer that was draining the battery.
