SL/R107: Just stalls
you want to check fuel pressure, system and control at the fuel distributor. Parts houses have test kits you can loan out but you will need some additional fittings
at 90 k I guess new fuel injectors could be in order. But I think bad injectors which no longer atomizer but shoot a stream of fuel will make it run rough but not cause a stall.
doing searches on KE Jetronic will swamp you with a lot of good info.
ignition wise you might want to consider new rotor, distributor cap and maybe ignition coil and wires. Spark plugs too.
hopeful lot the guys who know these engines will chime in.
