PTS, It would be helpful if you posted the year of the motor. Different years had different ignition systems, and therefore different failure modes.

My '77 Merc 150 will cut out if the fuel pump cannot keep up with the fuel demand of the motor. It also cuts out if the power from the ignition switch to the switchbox is interrupted.
