I have a '08 135i and had this issue as well, but it ended up being my fuel pump assembly with the fuel level sending unit (in the gas tank).

From what I've read and heard, the N54 motors are prone to hpfp failures, so you may be right to assume that. I'm including a link to one of our site's DIY tech articles on the fuel pump test and also to an earlier thread where this is discussed - hope this helps you out a bit in troubleshooting.
