Appears to be a loose electrical connection. I would have the ECU tested.
I had the exact same problem on my 535i it ended up being dirty spark plugs, if you haven't changed your plugs in a while i would reccomend it.
Plugs are clean and new. Fuel tank is filled to brim. I find no binding in air flow sensor.I have put contact cleaner on all wire harness connectors under hood. Perhaps it is a dreaded ECU problem!!
