I had a similar problem with my 535i. My problem turned out to be the fuel pressure regulator, but I ran through the fuel pump, and fuel pump and main relays before I really found the problem. Check the fuel pumps for operation (Bentley is pretty good on this...) and that should help you isolate the problem. Assuming the pumps are running, you can check the fuel pressure and fuel pressure regulator with a tee and fuel pressure gauge. When this problem started for me, it was intermittent, and the car would hardly run at all.

hope this helps,
