2000 Dodge Intrepid idles low and stalls.

I have a 2000 Dodge Intrepid with about 107,000 miles and when I am driving at low speeds (25-50 mph) the car is putting out about 1500 rpms but may shoot up to the normal 2000 rpm range. When driving on the highway the rpms are closer to 2200-2500rpm, driving 65-75mph. Most importantly, when slowing down to make a turn or at a stop, the car will once and a while stall. I am able to start the car after a couple turns, but have been making turns at a slow speed and lose my power steering and brakes. A little tough to navigate if there is an uncoming car!
Hope someone can help!
Thank you.
