I had a similar problem right after I purchased my 525 almnost a year ago. I replaced the fuel pump relay and the main relay and the problem never showed up again. Also when was the last time you changed the fuel filter. This same thing happend on an e28 535i.
I'm sure that someone here will have more info.
