When I first start the car it sputter and sometimes cuts off. Once it gets going it seems to be okay. I am afraid I will get stranded when it will not start.

Is there a check engine light on? If so lets run the codes to see what comes up.

If the check engine light is not on I would start with a tune up using all AC Delco parts with a throttle body cleaning. Here is a guide that will help:

Please run down these guides and report back.
