I have a 2000 SLK 230. Intermitently it will "stall out" when I am driving. The yellow triangle in the middle of the dashboard will flash and I have no power when I push the accelerator. I take my foot off the gas pedal and let it coast until I can slowly regain power. I am always able to get it to power back up, but on the freeway this can be really unnerving. It seems it might happen more going uphill, but sometimes happens on the flat and it might happen more before the engine is really warmed up. I took it to my mechanic who could not get this to happen. He even had the transmission people check it and everyone thinks it works just great. Help please
