Gas Recirculation Valve (egr Valve) problems of the 2015 Nissan Versa

I was driving down the highway, in traffic, 30 - 35 mph, outside temp 88 degrees, ac was on, full gas tank, highway I-35 downtown dallas in the middle of rush hour, the car abruptly stopped while driving and turned off. The steering wheel did not respond, brakes did not respond, all warning lights came on, the car coasted to a stop. I put the car in park, waited 10 seconds, cranked, gassed it and it started back up. I took the car to o'riely's auto parts in cedar hill 30 min. Later to run a diagnostic test which came back that the battery, starter, alternator were functioning normally.
