I have a 1987 300E US automatic sedan. In short, the car likes to stall when making a right turn (used to be a left turn but has now shifted to the other side). The problem usually manifests itself after the car has reached operating temperatures and has been running for a while. Warmer weather brings the onset of the symptoms earlier in the operating cycle. The vehicle will run fine but will initially sputter when making a right turn. Shortly thereafter, it will start stalling on right turns and eventually will sputter and stall when decelerating to a stop. The car initially restarts right away, sometimes while the car is still coasting and you shift into neutral and crank.
Eventually, you have to come to a full stop, put it in "Park" and then start cranking - which takes a couple of more attempts before it starts up again, and sometimes it helps to relieve pressure from the gas cap but not always. This used to happen sporadically, over the past two years, and has been impossible to diagnose. Now it happens every time the car runs in stop-and-go (not highway) traffic for more than maybe 30 minutes.
