It almost sounds like the engine is going into some sort of limp home mode. If it is not shaking violenty (as if several cylinders are out) then I would venture to guess some electrical component is failing, as in a sensor. I think if the fuel pressure dropped, it would run extremely lean, but would miss shake, etc, as well.

I may guess: hall sensor in the distributor, MAF, possibly crank position sensor (though it seems like it wouldn't run at all, if that crapped out). ALSO: I wonder what would happen if the idle switch remained engaged (as if throttle is at idle), even though you were wanting to accelerate away from stop? If it happens again I might check this first with a continuity meter.

I think the computer stores the codes, since it ignited the check engine light, can you pull the codes? I think you need a BOSCH Hammer or similar to interface w/ the computer.
