sounds like your alternator.

you could go to checker, sorry, o'rielly auto parts or even pep boys to have the charging system tested.

wherever you take it, make sure they use the amp clamp, some places only check for voltage.

Check this b/c it causes all kinds of electrical problems; http://www.lexls.com/tutorials/lighting/bulbout.html
If not i would say it might be your alternator starting to fail. Are you leaking power steering fluid on your alternator? It's a very common problem which kills the alt.

100% it your alt. Happened to me last month, change this soon because the car will not last more than 30 mins or so on battery power alone. You don't wanna have to push a 1LS by hand... Trust me on this ='(.
