I had similiar symptoms a while back, though on a different car. Initially I assumed it to be the fuel pressure regulator, which I tested and it checked out fine. I then decided to replace it regardless, got the par number wrong and replaced it with a unit rated at a much higher pressure. Problem went away. Turns out the actual problem was what I was told a "dripping injector. Essentially the injector didn't shut down between fires, but kept letting fuel past, which dimished the overall fuel pressure to the point where the car "missed" intermittently. The same injector would leak into the cylinder after shutting the car down, which would lead to the cylinder flooding with fuel, making starting the car near impossible.
