Id double check your fuel pressure, and make sure that it is ok, it could be dropping too low, causing the stumble and shutdown. Or you could have a sticky fuel injector that could not be firing everytime.

Inspect your spark plugs and wires as a misfire isnt always detected if a spark successfully grounds whether its on the spark plug itself or the block.
