I think my fuel pump is going bad but unsure

Hello All,

I am trying to figure out what is going on with my jeep but I am unsure exactly what it could be. I have some idea but nothing solid. I'd like to say what is going on and hopefully someone can give me some idea of what might be wrong.

I have a 1994 2.5l Jeep Wrangler. I got home from it last night and everything was working perfectly but this morning it didn't really want to work. It too me 3-4 tries in order to get it to work. Once I got it going I had a check engine light and it was hesitating really hard. After giving it some fuel and waiting awhile it got its revs back up to where it should be. I drive it but once I get to a stop sign it goes back to the way it was. It shut off on me once or twice on the way home and I had to wait for about 5 minutes. Then I started to drive on it again and ended back up in the same boat 10 minutes later.

I think it is a bad fuel pump or fuel filter but it could also be my O2 sensor. Someone mentioned it could be a cam or crank sensor.

Will Start but then immediately turns off
Started (After several tries)
Goes to normal (After giving it gas and little it idle for awhile)
Drive around
Come to a stop light and it goes back to acting up

Any help would be greatly appreciate.

Thank you,
