What is all done to your car? You need to make sig with all of your mods to the car. From what I have read I would say O2s or crack in the intake elbow if it is a stock elbow.

Have you checked the coolant temperature sensor in the water pump housing? If its not telling the PCM the engine is warmed up, the PCM may be setting too rich an A/F ratio.

it sounds like it may be going into a limp mode so it doesnt hurt anything else on the car. it sounds like you may have an air fuel issue tho... is there anyway you can check them???
