Stop by a parts store and have them test your battery and alternator.
Get some white out and draw a line on the face of the crank pulley from the crank bolt to one edge. Drive the car and turn on the a/c and/or rear defrost. When you return home, check that the line is straight. That pulley is actually two metal pieces connected by a rubber piece that can can break and possibly cause this problem.
Does your check engine light turn on while diving?
Battery is 2 weeks old and I have tested the alternator and it checks out fine.
I'm thinking its the pulley. And no, no check engine light.
