Carrier/rack problems of the 2006 Dodge Charger

I was driving along coming to a stop, when the car cut out. Just flat went dead. No power, no lights on the dash, no real ability to brake, no power steering. Nothing. Lost all power. Came to a stop in traffic. It sat there for about 5 mins then started back up. Took it to the dealer (big valley Dodge in van nuys, CA. - now out of business) but they couldn't find anything. Didn't happen again til about 5-6 weeks ago. Making a left hand turn in traffic. Just as I finished the turn, the car went dead. Basically the same symtoms as before. Started up in about 3-5 minutes. I reached my destination (working out at the track). 1. 5 hours later I had someone follow me home. Within 3 blocks the car did the same thing. Called Dodge corporate. They told me to take it in. Took the car to what used to be big valley but now is the superstore and had them check it out. They found nothing. About 3 week ago, it happened again but this time on the freeway in rush hour traffic. Luckily the traffic was so slow that I wasn't traveling at a great rate of speed. Again I was able to start it up. This time I had someone in the car with me. This car is a dangerous weapon and an incredible risk for any one who drives it and anyone who drives in front or behind. Something has to be done.
