Owners/service Manual problems of the 2009 Chrysler 300

I have a 2009 Chrysler 300 that intermittently shuts itself off while driving. When it does this, it loses al power. Lights, flashers, dash lights all turn off. I lose power steering, power brakes and have to manually steer it and brake it to get it off to the side of the road. Once it is out of traffic I put it in park, turn off the key and then, and only then, I can restart it. When all of this happens, there is no codes. I took it to the dealership where I purchased it and they said that everything is fine because there isn't any codes. I called Chrysler customer service and filed a case. #78850950. They claimed to have any prior knowledge of this happening on any other Chrysler product. The last time the car shutdown I was making a left hand turn and it shut itself down as I was going across a very busy highway and it almost caused an accident as cars swerved out of the way so not to hit me broadside. Neither Chrysler or it's dealership will help me get this problem fixed stating that they have done everything that they are required to do and that the diagnostic machines says there isn't a problem. I suggested that they take the car and drive it around because it will indeed repeat in a couple of days time. The dealership told me that since it's a 2009 that I would be better off getting a new car. I told them that I want this one fixed. They told me that it would cost me thousands for them to hook up test equipment and drive it around. It is in my opinion that this is a safety issue and it will be only a matter of time before someone is killed. There are several similar complaints on the internet. I offer you this car to inspect and drive and see if what I am telling you is in fact what is occurring. What bothers me the most, that this car shuts off all the power and there isn't a single code being generated by the computer.
