Trax is shutting down while driving, It has happened 6 times now, Most recent my dash goes black last until you turn it on and off, WTH

While driving my whole electrical in the car went black. That meant my actual visual screen, my dashboard, my lights and side everything became a very scary situation to where I was not for sure what to do. After cutting off the car and restarting it, the electrical problem did not stop. I had to wait for a few seconds more before it came back on.

I was driving down the road and the vehicle abruptly lost electrical power and stalled. I could not put on hazard lights and had to pull over. The car started within a few minute minutes after and the same issue happend about 5 minutes later. Luckily I was not on the freeway. This was a very scary situation as my two young children were in the car with me. The dealer cannot figure out what caused the issue and could not replicate it so I'm stuck driving an unsafe vehicle until my lease is up.
