Very sincere owner. Would rather fix than play lemon. Car usually stalls when accelerating or decelerating at slower speeds(15-40MPH). Classic scenario: Slowing down at stoplight and engine cuts out, or....merging onto onramp and begining to accelerate. Tank is always at least 1/4 full when this happens. Dealer has found no codes on diagnostic, and refusese to do any troubleshooting. I tried another dealer, and they just 'drove' it. Both claim non-reproducibility and 'mea culpas'. My wife and I almost got creamed Friday night when it stalled on a freeway onramp. We love the car, and it has only just(32K miles) started doing this. Help help help!
