sputtering randomly while driving

2002 cavalier with 115000 miles. Daughter claims the car idles fine but periodically sputters while driving and acts like it wants to die out but never has. Plugs are 2 years old. Fuel filter(s) have never been changed. Any help will be appreciated.

my 2001 does the die out thing too. Ive noticed it only happens when my fuel gauge drops below the 1/4 mark and it only does it if im making a sharp turn. im thinking fuel filter but hoping i can get it thru till spring.
