first thought is that the catalytic converter may be plugged. when plugged the engine will run until it builds up enough back pressure to kill the engine. after it sets a while the pressure is released and the car will start again. you should be able to start it up and observe how much force your exhaust pipe has. it should be strong at first then decrease to almost nothing before it dies. try that and check back.
remember that any of the new parts could also be bad so you may need to do a pressure check on your fuel pump

did you try to remove the code # with a diagnostic code retrieveing tool, this will remove the light from being on in the system, providing the computer is functioning properly, if you do not have the tool to do this with, then disconnect your positive battery cable, for about 1 minute, then reconnect it back up, and see if light is out. you will have to reset your vehicles clock, and possibly some radio functions.
