Starts when cold and dies

The car will start when cold and run for about thirty seconds then die. I was able to drive the car at night, but it died in the driveway and wont stay running. I replaced the fuel pump and the CPS and it would start and run when cold for about thirty seconds and then it died. It would not start back up. I cleaned the throttle body and it still will not start. I started having problems immediately after I filled up with gas. The tank had about four gallons in it when I filled it up. Died right after I filled it up and started about four hours later. It ran for about ten minutes then died. Started up about three hours later and died going up a hill. There was some hesitation at first then it just died. I let it sit for several hours then it started back up and ran for a few minutes.
