I had this *exact* same problem when I first put the Cooper S I bought
in 1996 on the road. It was a combination of engine vibration (normal)
and a too-high fuel-pressure from an after-market electric fuel pump
(ten pounds, way too high).

I added a $15 in-line pressure regulator from the local hot-rod shop and
set it at 2 pounds and never had the problem again.
