Car Will Not Start problems of the 2019 Chrysler Pacifica

The vehicle stalls out while actively driving it down the road on a city street. The vehicle stops mid driving, immediately shuts off, loses all power, and engages park by itself. The vehicle then fails to restart and leaves driver stranded in unsafe conditions. Happened the first time driving 40mph down a city road. Driver was almost rear ended. After 20 mins driver was able to get it started again only to have it happen half a mile down the road. Had the vehicle towed by Chrysler to the nearest dealership. They found no stored errors and said nothing was wrong. They installed a flight recorder in the vehicle and we picked it up yesterday. 10 miles away from the dealership while driving on another city road the vehicle again shut itself off while driving, had a complete loss of power, and locked itself into park mode and wouldn't restart. This time had my entire family and two young children in the car trapped in the middle on a busy intersection. Vehicle was then towed again to the same dealership and they claim the flight recorder didn't pick up anything. A claim has been opened up with fca headquarters and again no one is assisting in this issue. This is a huge safety concern and needs to be addressed.
