Transmission Not Engage problems of the 2006 Chrysler 300C

I was driving north on the njtp and was in the process of passing another car when suddenly my car went into neutral or disengaged from the transmission. The engine accelerated, but there was no power transferred to the road. I had to pull into the break down lane and turn off the engine with the hope that the electronic module would reset itself so that I could engage drive gear. The procedure worked, but now the transmission readily disengages from drive with light to moderate throttle application. Clearly, there is something major wrong with the transmission or its electronic management that could prove dangerous to me or other vehicles on the road.

Most of the time, the engine will stall at a stop with all gauges dropping to zero. This also happens when the car is moving down the roadway. Engine does not start smoothly. Most times it takes at least two attempts to start it. Sometimes upon restart the gauges remain at zero. Upon start, engine will run for a brief time and will run maybe 1 block or so before stalling again. It will run without incident until the next episode. There may be a spread of 3 to 4 weeks between incidents. Sometimes the engine speed jumps up without accelerator input making the car leap forward. This has happened once to me. Sometimes when the engine is restarted and put into gear, the transmission does not engage immediately, but after a very brief delay causing a "jump" into gear when it does engage. The esp bas light comes on a majority of the time this happens. Sometimes the gauges all drop to zero while the car is running. Almost always, I can feel in the running of the engine that something is not quite (almost imperceptive missing) right before this happens. I took the car to a Chrysler dealership immediately after this happened and asked them to read the codes. They told me many codes had been recorded.
