Wow, it's crazy to see this comment because I drive the same type of car and recently experienced a similar problem.
The car was dead for long enough that I could get it towed to the mechanic and they educed it was a problem with the EIS (electronic ignition system).
The EIS computer was sent off to mercedes for diagnosis, they reported that the computer itself was fine but it was an issue with power. The mechanics traced it back to a bad connection of a wire somewhere.
