Lose Power Steering problems of the 2009 Chrysler Town & Country

Purchased a 2009 t&c 3 weeks ago, 47607miles. First incidence occurred after 1 week. While driving the vehicle lost power steering, (electronics, lights, radio, etc remained active), I realized the engine had stalled/cutoff. I was only going about 20mph, I had to put the car in park and restart the ignition. Car drove fine. Took the car back to dealership where they machined the rear rotors. Week 2, took the car back to the dealership again, they machined the front rotors. Week 3, while driving the same incident occurred, engine cutoff during operation without warning. Luckily I was in a neighborhood and speed was approx 15-25 mph. Electronics remained active. (there were no warnings or error codes when the engine shut down. ) had to put the vehicle in park and restart the engine. Took the car back to the dealership for the third time in 3 weeks of ownership where it currently remains as they try to chase this ghost. I am convinced this vehicle is dangerous and not safe to drive since the engine cuts off randomly. I asked first team Honda of chesapeake to take this vehicle back and I would buy a different vehicle. The used car sales manager offered me 75% of what I paid for the car 3 weeks earlier and told me there was nothing wrong with my vehicle. It is under warranty for 90 days so I will continue to send the car back and warn others before they purchase an unsafe vehicle.
