In my case it was a bad unloader relay but I also replaced
the fuel pump and main relays in my search. All are cheap
and I'd consider them as preventative maintenance on an
older BMW.

May also be a bad AFM but that's a LOT more expensive so try
relays first. Also worth cleaning all the fuses and the
connections to the Motronic speed and TDC sensors.
