While driving down the freeway at around 60 mph, I sharply accelerated to negotiate traffic and my vehicle lost power and the check engine light was flashing. I was able to roll to an exit ramp where i could barely get up a slight incline. I was able to get out of traffic but at speed of less than 5 mph. It sounded like the vehicle was running on two cylinders. I pulled over and turned the car off. I was able to re-start the car after which it ran normally. I went directly to the dealership where they were unable to reproduce or diagnose the issue.
