Hello and thanks for your question.
I have seen 1 of these as well as A 2010 Taurus SHO with similar complaints. Both of them I had to replace transmission range sensors on. No codes similar symptoms. Had to install a vehicle data recorder in both of them to get a snapshot of the range sensor data at the time of the symptom. One of them took over 3 weeks of the customer driving to get a good snapshot of the data. The range sensor would intermittently show neutral when the problem was occurring. I have seen neither car back since replacing the sensor.
