This can also happen with F10's,always refuel when gauge shows 1/4 tank. Appears one prob is following another in some sort of 'sympathy'.It is a V10 so maybe a diagnostic at an older M specialist may pinpoint what's causing it to chain react because it's strange one thing should follow another. Good luck!
*Oh nearly forgot, first thing to do is clean the Mass Air Flow sensors with special spray only if they haven't been touched for a while.
