ahhh haaa! so bought this 92 300e the other day and ran it around (before, during and after purchase) for a bout 2.5 hours. only thing i noticed was a mild stumble once or twice but that was it. didn't use it yesterday but did
start it to see if battery was holding charge.
today i start it (raining since yesterday) and warm it up for 10 minutes and everything is fine. pull out of the drive and it stumbles hard but then goes another 1/4 mile and dies. try to start and nothing, but the tach needle jumps up to 5k rpm when i turn the key. go back an hour later and it starts up and makes it home.
now i can start it and it runs for 2-3 minutes before the abs light comes on and the blower comes on (climate control is set to 'off') and it dies.... plus the power seat doesn't work when this happens and the battery acts as if it's dead.
wait for 10-15 min and car turns over fine and starts but then the abs light comes on after a few mins and it dies....
is it possible the ovp is getting damp due to the 2 days of constant rain? or is some other gremlin at work??

Do the same and see what happens. The next I suspect is the MAS relay in my cars, in your vintage car, you have three different relays to check and swap good ones in with.
Checking the ground strap is a good thing to do regardless (though unless you are running around without an engine splash tray or live in an area where they salt the roads, probably not the cause).
Make sure to let us know what you found.
