turn the car on and the disconnect the power from the battery. if it turns off then your alternator is shot. If not, take the battery to a auto part store (autozone, pepboys) and have them test it for free.

once your car is running, the battery doesnt matter, so if i died on you while running ,chances are its the alternator

Sounds like the alternator to me as well. If the alternator tests good, though, check the cooling fan control unit. If you notice your cooling fans coming on a weird times (like when the engine's cold, or several hours after you've stopped driving for the day, that might be the culprit. I had that problem, and it took a while to figure it out. Check out the testing procedure in your troubleshooting guide, it's actually pretty easy to troubleshoot once you figure out that might be the problem.

Good luck, and post your results.
