CLS 55 POWER LOSS!!???
My CLS 55 has 34k miles and in the past month lost power in three separate incidents. During those three times it was fairly warm outside (75F-82F) with low humidity. All three times involved similar circumstances; after driving swiftly for 2 to 5 minutes vehicle lost power for a short time. After less than a minute or two the car went back to what seemed its full potential. I want to emphasize that this took place after driving enthusiastically on a public roads for short periods. No track like beating or anything like that. Has anybody experienced this before? What are the usual causes? Any help is appreciated

Definitely have your IC pump checked. They fail intermittently and sometimes with no warning signs. Many people on here prefer to swap out the sock pump for a Johnson CM30 pump. It does not fail as often as the stock pump.
