did you ever get your battery replaced? i had to replace mine around 150000miles.
check the terminal conectors as well mine went bad and it drained my battery...if you get a chance replace them...
mine were lose and it ended up killing the battery as well

it seems to be doing the same mine did...soon enought it will happen every day

Go to your local auto parts store and have them check your charging system. It sounds almost like your alternator is weak, but it could be battery cables or your battery.

i took it to advance auto and they did a full scan and everything was good. the power will like come and go. i put in a new battery and not even 20 min into driving the battery light starts flashing then stays on. so now im driving with the ac on its blowing then slows down kinda like a pulse then goes away. i can tell at night the headlights are fine then they get brighter then go dim then bright again. i just dont know.

The alternator is new about 3 months old. Since I've put the new battery the volt meter has not gone down yet. I'm going to check the ground on the starter when I get a chance.
