2010 Mercedes Benz 200e Engine misfire

My mercedes engine misfire while driving and the engine sign at the dashboard turn on and the engine shake while driving and while idle. I think it misfire when I accelerated the car. After I stop the car for about 1 hour, the engine sound ok(no misfiring and not shaking) when I started the car. After driving for a while and I need power it misfires again Would appreciate your expert opinion.
