Hello all
I have a 1985 280CE Euro (66K), the car runs good, Had a used 110 installed about 2 years ago, but have not used the car very much. About three months ago I started using it regularly. I have put about 2500 miles on it since with no problems. This morning while on the highway, doing about 60 mph, the engine shut off. This lasted about 1 - 2 seconds, and the engine came back on. This happened 3 times with the same outcome.
The lights stayed on, the only thing I noticed was the tach went to zero. Each time the engine came back on after a couple of seconds. I am thinking electrical short, but where should I look.

Thanks
Jack
