Take it back to the dealer, since it should still be under warranty.
You could always check the bimmer forums and see if anyone else has experianced the same issues.
Most likely a high pressure fuel pump failure, very common with the 35i models with N54 or N55 twin turbo/scroll engines. Dealer should replace it for free, warranty for the HPFP is 10 years or 120,000 miles whichever comes first. Many 35i owners reported multiple failures, 3 failures and you qualify for lemon law, at least in CA.
