It could be a weak battery. What I want you to do is take the car to the parts store and have them load test the battery. If it is good, it will maintain a set voltage under a load. If weak, it will drop off. If the battery is good, I want you to check if there is a constant draw on it. If there is, remove one fuse at a time until the draw stops. THen we will have narrowed it down to a specific circuit.
Here is a how to for checking for draw:
If you want to test the battery yourself, here is how to do that:
Let me know what you find. Honestly, if it dies that fast, chances are the battery is no good, but these test will help determine it.
