1995 Mercedes S500 Questions??
 

I start up my car and it runs for 20 minutes the most. While the car is running smoke comes from the exhaust with a smell of gasoline. The car shakes then stalls after 20 minutes. However if I push on the gas pedal the car stays running for a little longer. When I try restarting it, no luck. I can successfully start it after 2 hours or so. There is no check engine light on.

Could be a fueling issue. Might want to have an indy shop take a look and see what it might be.
