Datalog the car and check the fuel rail pressure sensor. Pull a coil and plug and sit the end of the plug on something metal. Turn the car over and check for spark.

harbor freight sells a cheap fuel pressure gauge --- i used it about 10-15 times before it failed but it helped me diaganose the problems on 3 cars over a year or so.
