Curry, mine's been doing the same thing. It's actually in the shop right now get a full tune up, but I'll tell you the steps I took to fix mine.

First off, I bought it w/ 49,800 miles on it and I'm very willing to bet the dealership didn't perform the 50,000 mile tune-up.

When the problem started happening, I adjusted the idle manually (big mistake) so I could keep it running to get to the shop. I had the fuel injectors cleaned and that fixed the stalling problem, only now the thing was reving to high from where I had adjusted the adle. After looking around, I found out my throttle position sensor was messed up, so I had that replaced and the throttle adjusted properly.

Get my car back today, so I'll let you know how it's running, but your symptons sounded identical to mine. Also, check your air filter...mine was a little dirty and when I cleaned it, the idle smoothed out a little better. Maybe just a mind trick, but you never know...
