Unhappy 2001 V6 Engine runs but only at idle speed.

Need some help. I own a 2001 V6 Mustang. While driving last night it was running fine and all of a sudden it missed a little, then about 20 seconds later it lost all power and came crusing to a stop only to idle very rough. I turned it off checked the oil and all the obvious things and then re-started it. It started but would only run at an idle (very roughly) even if the accellerator was on the floor at full throttle. I tapped the throttle up and down rapidly and then the engine seemed to return to a normal operation. I drove the car home (about three miles from where this took place) and pulled it into my garage. I then shut the car off, waited a few seconds and started it again. The car started but wanted to idle really rough again. When I gave it some throttle and ran the engine at around 2000 rpm for a few seconds, and then let off of the throttle, the engine seemed to once again run ok and idle smoothly. Every time I stop and restart it, it does the same. I have not driven it again for fear of getting stuck on the side of the road. I pulled the fuel filter off, and the fuel that drained out onto a paper towel looked sort of dirty. I can blow throught the filter although it does seem to have a little restriction and thought I would replace it to see if this could be the problem. Has anyone else had this problem? Could a slightly restricted fuel filter cause these symptons? My only experience with fuel filters has been either the car runs or it doesn't. Any advice would be greatly appreciated.

Thanks fellas.
