Re: SRT6 power issue
If it only happens when the car is warmed up, and then goes away "on it's own" when the car cools off, then it is the IC pump. Mine failed on a trip to Hamilton ON and I could feel it disengage (then the car had less power than my roadster) but after 10-15 miles of driving the engine would cool off and it would suddenly start working again. The car was under warranty so I printed out a couple threads describing the problem and had the dealer replace it. It took them two test drives to establish the problem -- they did not get it hot enough the first time and this was the first SRT6 they had seen, so they were unfamilar with the issue. But they replaced it two years ago and it has been fine ever since.
