Why my car will not stay crank unless my feet os on the accelerator? on 2005 Ford Taurus

when I crank my car I have to keep my feet on the accelerator to keep it running.When I stop at a traffic light I have to keep my feet on the accelerator and the other feet on the brake.This also happens when I'm backing out of my driveway.
