Michelle,
When this happens, take a voltmeter or a multimeter to see if the battery is at 0v. If it is, replace it.
What you described sounds like a bad connection. Please take a look through this link:

The reason I'm questioning a connection is this. If the battery is good and it drains that fast, you would see something smoking. There aren't any wires on the vehicle that could drain it that fast without overheating.
In addition to the link, check the connections at the starter. I really want to help you get this going. Let me know as much as you can.
