general problems of the 2001 Mercedes Benz SLK

Mercedes benz Slk320 just dies out while driving. No warning lights or anything before the motor stops and the car loses power. Happens sporadically. Mercedes benz cannot detect the direct problem even after diagnosis. Continues to blame it on something else, then fixes it, but it continues to occur.

I am an owner of a 2001 Slk 320. I have had chronic problems with headlamps and brake lamps going out , bulbs melting in lamps on brakes as well as headlamps. In the beginning these repairs were paid under manuf. Warranty. However, I am paying for replacement bulbs, most recently a headlamp problem I will have to have replaced at a cost close to $600. Today I received a recall from mercedes notice for the brake lamp problem. I question that the same may be true of headlights. My condition of brake and headlights being replaced as well as a brake lamp replaced in the past, was so chronic, I ordered and paid out of pocket for electrical testing on my car where nothing wrong was discovered. My point here is that I feel in addition to the brake light problem addressed by mercedes in my recall # 2006-080005, I believe it would be remiss for safety purposes to not announce that I believe the same condition applies to my Slk headlights. Also, for such problems on the brake lights that existed in the past, what recourse do I have in monies I laid out of pocket, pertaining to the chronic brake light problem in my Slk 320. Thank you.
