My guesses would be:

Throttle position sensor, check the voltages closed and full open (naturally with the engine not running)
Temperature sensor, this will control to a degree leaness for fuel.
Map Sensor: drop in pressure will greatly affect the motor. More load could be loss of pressure. Possibly cracked hose you can't see.
IAC Idle Air Control. this will affect how much air fuel mixture you get. You said it acted like it chokes out...THIS COULD VERY WELL BE IT. Could be stuck in a open or closed state.All else fails after these...go to junk yard and get duplicate ECM. Computer could have taken a surge and messed up eprom.
