04 f150 5.4l runs for a few seconds then stalls out

P0451, p2196, p2198. Burning rich. I have replaced the power steering pressure sensor, purge valve solenoid and the fuel pressure sensor and still no change. Any ideas before I have it checked out by the dealership scanner would be greatly appreciated.

Update: after driving about 50miles since I replaced the fuel pressure rail sensor and filling the tank up with gas the check engine light has went out, so maybe pcm didn't have enough time to make the appropriate fuel changes until so many miles or filling up the tank has something to do with it. I will see if check engine light stays off when fuel gets low.

Sounds like a stuck injector or two... I would stop driving it and starting it.
