Load test the battery at an Auto parts store.Replace the Battery if it's Crap!..also check your Alternator Connections and make sure they are Clean and also your battery connections.

So, the battery is fine, and the alternator is charging.
So when you turn the car off, does the car start back up, or doesit feel like it doesnt get enough power to crank?

You probably have a drain on the battery while your car is off. Test for one.

i have the same problem, i'm only getting 12 volts though. battery is good, alt is good. the car will start multiple times, but it eventually drains to the point none of the interior lights will come on. i dread looking through the wiring.

Probably already tried this, but check that all the bolts holding the Alternator on are tight. I had a loose one and the car would run out of juice in a couple blocks.
