I had a very similar problem twice in the first two weeks of owning my Crossfire (April/May '05). Advised dealer and techs could not duplicate it, so they would not do anything. No issues all summer myself. My husband mentioned that it did it to him in the last month.

I will be very interested to hear how your dealer handles it.

It's crazy because, it works fine 99.9% of the time, then these odd incidents. My big fear is that it will quit the day after is no longer under warranty.
