I am new to this forum, and to mercedes. I own a 1990 300ce, which I like; however, it has a bad habit. If I do not use the car for a week or more, then after I have run it about 10 minutes it will suddenly shudder and stall. It will restart only to continue to shudder and restall. If I let the car sit for about 15 minutes it will work ok. If I drive the car every day I do not have this probelm.

Anyone out there had a similar problem

Thanks
