2001 Chrysler Concorde

Engine problem
2001 Chrysler Concorde 6 cyl Two Wheel Drive Automatic 130, 00 miles

I just brought a concorde from a friend. I got a great deal because no one can figure out whats wrong with it. Well the vehicle starts normally but after driving for a little while it starts to sputter. Now I do know is that this sputtering starts right around the same time the engine warms up. This continues until I stop driving or basically until the next time I drive it. I think that the fuel filter or the fuel pump is the problem but I am not very mechanically inclined so any advice is welcome. Thanks for your time.
