Sounds like a misfire, leaking injector, failing fuel pump or could be something else. It's really hard to tell without running a few tests and checking for diagnostic trouble codes in the computer. I suggest starting with checking those codes with a scan tool.

It started doing it when i would drive, maybe once or twice a day. Now it does it right when you start it. I cant even get out of the driveway. What do i need to change on it?
Gas will not enter tank without the pump shutting off every two tenths of a gallon
abs and brake lights come on whenever im going over a small bump or pot hole it also says to se...
