Just dropped my SRT6 off at the dealer today for the same problem (Supercharger disengaging once the engine gets up to operating temperature). They were very impressed with my knowledge of the car's systems (all derived from this thread). The Crossfire Tech rode with me and the car did exactly as I described that it would. He took my word for the diagnosis and my pump will be here in a few days and they have already replaced the temp sensor. Should be back in it by this weekend. I'll keep everyone posted. Now I just have to get around to installing my new ASP Pulley kit.
