Well I took my to the place my wife bought it (Koons at Tysons...in Virginia). For the first time ever when I have had an intermittent problem it happened with the service foreman in the car!
It happened 3 times...pedal to the floor acceleration non-existent. I printed out the FORUM entries from the Crossfire FORUM and the MB FORUM and told him that the STAR D/B should have this logged because they directed a repair on another Crossfire.
My main question is whether the water pump fix will also correct the transmission "bog down" that happens intermittently causing whiplash.

I'll keep you posted.
