I limped to the nearest exit and powered the car down turned it back on and problem was gone. I'm afraid to put my foot on the gas now in a 85k dollar 439 horsepower car. Going up to BMW after the holiday to have it checked out.
Sounds exactly like what happened to me about 6 months ago on a trip to Lake Tahoe, although the problem didn't go away by restarting the car. When I took it to the dealer, they replaced the low pressure fuel pump under warranty. (The HPFP had been previously replaced.)
