the other day i went to get gas. after getting gas i went to start my car and it died. then i tried it again adn it started but almost died. well i turned it off and tried it again adn it did hte same thing. so i went on home wich was not far from the gas station. i got home and turned it off adn started it again a few more times and it still did saem thing. then the next day i went out and tried it again it seemed to start a little better but still had trouble starting. so i decided to drive up my street and it almost died while driving. what could be wrong?
