Sounds exactly like the problem I had on my 260E. Would stall at stoplights. Also if parked for short stop it was impossible to start unless I let it set for a few minutes. Solved completely by replacing the fuel relay module. (located behind battery in engine compartment). A 200$ item but solved the prob

stalling 300e
I ad similar problem....in the shop like 6 times. The last time they replaced the "crankcase sensor" and it hasn't happened since. i also noticed car was running hotter than normal...this seemed to go away after i changed the oil. i wonder if it had broken down so much it wasnt lubricating well. no stalling since I did those 2 things. I don't know what a crankcase sensor is or does.

May also be the Potentiometer which is located on the opposite side from the EHA (Electro Hydraulic Actuator) Another cause could be the MAS control unit (near battery with a black I/O dial on it) it's a relay for both the fuel pump and AC compressor if the compressor doesn't work properly also then the MAS may be the issue
