Good stuff! Thanks Peter! Even though I don't have a vergasser, I
might again sometime in the future. Other than the M116, I have been
fortunate enough to get rid of them before I had to do major work.

Is your mechanic familiar with KE-Jet injection? It's mechanical, not
electronic except for mixture control feedback. A failing electro-hydraulic

A sticking idle control valve will cause stalling when coasting to a stop.

Or fuel delivery issue even if the pump is running or at least making noise.

Starts, runs and drives smooth for a few minutes until the temp under the
hood rises, at which point it cuts out. I'm thinking electrical.

Not it if's barely running or rattling -- my TE would do the same thing until I
replaced the relay and the bad pump.
Check the fuel pressures, if not steady it's a pump or relay.

Are you saying it got worse? I am assuming these were used parts so maybe they
are worse than what was in the car?

Latest update: Replaced both the coil and the ignition module, and it's
now stalling out after 5-10 minutes of operation. I'm thinking ECU,
myself. Anybody got any W124 ECUs knocking about? :D

The picture matches what I have, though the numbers are different.
The unit that I have is from a 260E 1989.
The ignition should not be any different other than the vacuum control

Is there any way to test for a flaky coil? Other than replacing the coil,
that is. :)

Yes, and you still may need to replace the coil. They burn out fairly
often.
Once on the Dotsoon? I had a loose spade connector at the ballast resistor.

I have had Bosch fuel pumps refuse to run properly when hot, although in the
case of the sedan it would have to be both of them. On the wagon they are in
series, so just one cutting out will cause stalling.
The one in my Audi Fox did this to me on a long trip out west in 1980 -- would

Can you hear the fuel pump running when it dies?
If you replace the fuel pump relay with a jumper, does the stalling cease?
