Does your oil pressure gauge work? I had what sounds like a similar problem in my 1988 300E. It puzzled the hell out of me. The clock would keep time when off but as soon as you started the car it would stop or go slow. My oil pressure gauge quit, but my tach worked but was very slow to react and never would go past 3000rpms. I took out the instrument cluster and took it apart and found a tracer on the circuit board that wasn't making a definite connection. A little bit of solder and I was set. By the way my problem started when I pulled the instrument cluster and accidently touched the + lead for the clock on the ground and caused a short which blew the fuse as well.
