Engine Shut Off Without Warning problems of the 2011 Ford Fusion Hybrid

Vehicle did a hard stall in the middle of an intersection on three separate occasions. It completely shut off with no warning. The first two incidents happened in the space of a few minutes. After the first incident the car was turned back on and there was no indication anything was wrong. Continued to try and drive it a short distance to get back to the parking lot. It than stalled again turning into the parking lot and a battery light came on. Battery was replaced but the vehicle stalled again a few weeks later during a turn with oncoming traffic. No warning, it jerked hard than just shut off. I'm not sure at this time what is causing it to stall. It seems to be happening when switching from battery power to engine power while making turns. Leaving the car stuck in the middle of the intersection with no engine power, power brakes or steering and oncoming traffic.

While driving from los angeles to phoenix in the summer, the car suddenly flashed a red warning light, and shut the engine off with the car moving at freeway speed. After pulling to the side of the road, and turning the engine off and on again, the car gave no indication that something had happened. It shut off again ten miles later, and again, and again. I turned around and brought the car home and took it to a dealer. They replaced the hybrid computer, but it did the same thing again driving to las vegas a few months later. The dealer cleaned the throttle body, and said everything was good. It has since done it again and again, sometimes just merging onto the freeway near my home. Repeatedly, the car has lost power - usually on the freeway, and often with my family in the car. I try not to let my wife drive it at this point, because I'm worried that she'll either get stranded with the kids, or get hit by someone when the car shuts off on the freeway. We no longer drive it significant distances.
