Not sure on the 300 but the 190 the ICV is right in front of the fuel tower. You can tell it by the two rubber hoses running from the manifold to the intake.

A combination of old, hard hoses and a dirty ICV will do this -- valve closes to slow the car down, then fails to open as the rpms drop, causing a quiet stall -- engine just quits turning, no shaking, etc.
Clean the valve by filling with carb cleaner, covering the holes, and shaking for 15 sec, then dump the solvent, until it stays clear. This will take a while, probably tons of residue in there. If the idle control hoses are not fairly soft, replace them. If you get occasional stalls while just driving, replace the fuel pump relay. Peter

Another Possibility
I once had that same problem with my '88 260e. It started as an occasional stall and became much worse over the course of several months. The problem turned out to be the airflow sensor pot mounted on the front of the airflow sensor. It wears out with time and causes the problem you describe, especially at idle and when coasting to a stop. Try a search on "airflow sensor pot".
The Bosch part is available from Olyparts.com. It is kind of sensitive to replace but not horribly difficult. There are other causes of stalling that should be investigated before assuming the pot is bad. John
