Can you elaborate on the sputtering? Is the car turning over, then the idle is out of whack and it stalls, or do you mean that the starter is sputtering and it never turns over?
What year is it? Any codes, other issues?
A failing CPS will often not throw a code and will be finicky when hot, other suggestions based on limited info: fuel pump, or a very dirty throttle and/or control valve. Again, these are guesses based on limited information.
