2000 Ford Taurus Low idling and stalling at times

Approx. A month ago, I had one incident wear my car when started idled barely and the rpms would slowly decrease and then die, after several of restarting and same thing happening once I gave it the gas quicly it would go and take alittle while of driving before it seemed that the car ran smootthly. Now the last week or so I am having this problem almost everyday. At times it runs fine, but then it starts to have a problem when come to stop, with low idling and then quiting. Restarts fine but just have to hurry and give gas before it quits on me? Help
