Car Will Not Start problems of the 2013 Volkswagen Beetle

Takata recall on 8/13/16 while driving this vehicle without warning, the engine shuts off. I was traveling about 45 mph on a city street and as I attempt to move over the engine shut off and I could not steer the vehicle. After coming to a complete stop I was able to restart the vehicle. The vehicle did this several more times before I was to send it back to the car lot. I was told that the crank shaft was repaired on the vehicle. On 9/13/2016 (1month later) while traveling south on a busy city street at approximately 45 mph, in front of an 18 wheeler this car shut of and immediately restarted on its very own. I moved over to a slower lane to prevent any accidents. I proceeded to my destination and without any warning the vehicle engine shut off again, only this time I had to manually restart the vehicle. I parked the car at an area restaurant for at least 2 hours. I went out to start the car and there was no power at all. I called tripe aaa, they checked the battery and the car still would not start. Finally a tow truck was dispatched and arrived about 15 mins after the battery check and all lights were own. In about 10 mins I attempted to start the vehicle and it started without any hesitation. I have not driven the vehicle since because I absolutely fear for my safety.
