Do you have a multimeter? Check the voltage across the battery. It should be ~12.4V. If it's below this you're battery isn't holding a charge. Given the fact your battery is new I'd say alternator isn't giving it juice to charge it.

If you can, jump the car... unhook jumper cables and check the voltage on the battery. It should be 14-ish volts. If it's low, almost certain it's your alternator. You can check alterator output with a multimeter but it's a little more complicated.

Goood luck!
