I had this issue FOR A COUPLE OF YEARS, the dealer couldn't figure it out, the local Mercedes indy shop couldn't figure it out either … in my case, it turned out that it was the fuel pump relay (the little $20 or $30 part) in the trunk fuse area.

Once it was replaced the problem was fixed. I hope it's this easy for you.
