In your first post you state that you were "accelerating from a red light". You may have to take this matter up with Santa; you have been naughty. Please, for the sake of the rest of us, restrict your accelerating to green lights.

The reference resistor will not affect starting.

If the engine was running, and the car accelerating when the engine quit, it is possible, though not not very likely, that the cat suddenly became 100% blocked. Usually cat blockage is a gradual process. Have someone hold a piece of paper against the exhaust outlets while cranking the engine with the throttle open. There should be detectable puffing of air out of the pipes.

Perchance, had you refueled just before the engine quit?
