“While entering an on-ramp and just before merging onto the freeway the vehicle failed to accelerate and I lost complete power from the engine. The vehicle was still powered on, but produced no combustion from the engine. The check engine light illuminated and a message appeared on the dash stating to shift the vehicle into neutral. I pulled off on the shoulder and shifted the vehicle into park. I shut the vehicle off and started it back up. After doing so I had full power once again. This is the sixth time this has happened.”
