Engine Shut Off Without Warning problems of the 2011 Dodge Nitro

Driving on 2 lane highway and had to brake hard as another vehicle cut me off. As soon as I did (brake) my SUV shut off. . . All the lights flashed on the dash board. I immediately put the flashers on and hoped I didn't get rear-ended. I tried 3x to restart my 2011 Dodge Nitro- it finally started. I was near the dealership where I purchased the vehicle, I pulled in, told them what just happened. They hooked it up to the computer and reported 'no errors'. It was a near miss on a busy highway, and I am worried if this were to happen again. I don't feel safe in my Dodge Nitro. I was alone, but what if I had passengers, children, etc. ? it is definitely a safety issue when you brake hard and your vehicle just shuts off, wouldn't move. This is incredible scary. Someone or more than one person is going to be killed when they get slammed from behind and pushed into on coming traffic!!!!!!!!!!!!!!!!!!!!!!!!!!!.

While driving in the area about 30 mph the engine just shut off and had to fight to keep the car straight to come to a stop.
