Hi billsjoy. Four days suggests a relatively small drain on the battery. Look for a small bulb that isn't turning off, typically in the glove box, trunk, or under the hood. If removing the "Interior Lights" fuse stops the dead battery problem, besides lights, unplug the radio. Radios need a second power wire to maintain station presets and the clock when the ignition switch is turned off. That memory circuit is always tied into a circuit that is always live such as the interior lights, horn, or brake lights.

I have other ideas, but try these more common things first.
