I have a M103 in my 86 W124. I have had occasional bouts of that stalling and hard to start following the stall. I have found that by immediately, (or as soon as I could get a can) to put a can of fuel drier in the tank. Immediate relief. Mine seems to want to go through that stall/ no start about once a year. Outside of that problem, it is perfect. My choice is "STP" deicer or water remover.
