'86 420SEL lost power and stalls

[praba]

Hi, this is my first time posting to this forum. Seems like there are lots of people here who are very knowlegdible when it comes to fixing MBs.

I ran into a odd problem with my 420SEL (255K miles). Last week while driving on the highway (for 15 mins), the car suddenly lost power (the engine did not die) and pulled over to the side of the road. The engine continued to idle rough and finally died. I could start it up and it would rev up and die within 2-4 secs. I can keep doing this indefinitely.

I left it for a couple of hours and it ran for another 10-15 mins and did the same thing. Seems like when the engine is cold ( i live in minnesota - brrrr - its -5 today) it seems to run till the engine warms up and then it does this.

Any ideas guys? Thanks in advance for your help!
