Dodge neon

I have a 2005 dodge neon and it runs great, but after 30 minutes it will jerk and missing, but once you get going it does ok. If you give it gas while it's trying to go slow it's like it's not taking gas. Not plugs, if it was wires it would do it before 30 minutes. What could it be?

FIRST THING I NEED TO KNOW WILL IT DO IT IDLING? 1. Changed both o2 sensors ( I had a check engine light) 2. replaced fuel pump 3. replaced fuel filter 4. replaced spark plugs and boots So, if you are having this problem, I would suggest you check your spark plugs and boots, fuel filter, and get your fuel pump pressure tested. I changed the o2 sensors as well, I dont know if this was the cause or not, but if you dont have a cel code, then I wouldnt worry about them fixing your problem. . IT COULD STILL BE A PLUG OR A WIRE..SO HOWS THE FUEL FILTER AND THE FUEL PRESSURE CHECK/REPLACE THE FILTER..Change BOTHo2 sensors AND ADD TO 1/3 TANK A GAS 1 BOTTLE OF *zmax FUEL TEATMENT*

No it doesn't do it while idling

It runs great up to 30 minutes and then starts missing. I am thinking it may be coils?
