[A4] Help! Charging system woes

[james0hanson at gmail.com]

Hello folks! 
I'm having a bit of trouble with my 2001 1.8.
   Last week, it would intermittently cease to charge the battery.  Usually happened if I got on the gas and the rpms went up quickly.  On my way to the shop, it stopped charging completely and I had to be towed to the shop. Did not go to my usual shop due to the distance.  $900 later I had a new alternator, and all was well.   
Last night, with no warning, it stopped charging again!  I was forced to abandon it at a friend's house 30 miles from home.  I've driven approximately 100 miles on the new alternator.  
To further complicate things, the power is out in most of the Seattle area, so I can't get on the web to research, and many auto stores are closed, including the Audi dealer.

Does anyone have any suggestions?

Thanks,
Jim
