What are the codes 35 and 42, my car will start for about 10 minutes then dies. I have replaced the map sensor, the throttle position sensor, and the idle air control valve. Please help

DTC - 35 IAC problem or idle error

DTC - 42 Ignition bypass circuit error

Are you able to keep the engine running if you give it gas? Have you checked fuel pressure? Does it always start right back up?
