Have you cleaned your throttle body and IAC ? Ck your tps also . It is always good to keep your fuel filter changed on a regular basis . A pressure test will tell you about the pump .

Easy way to tell is swap the fuel filter first then try and trace your fuel lines and make sure there are no kinks after that if it still happens then there is a good chance it is your pumps.
