Jeep just shuts down while driving

My daughter has a 2015 Jeep Sahara with the V6 engine. She loves her Jeep. Unfortunately, over the last four or five weeks. It has just shut down on her about five times. She’s driving down the road and all of a sudden it’ll just shut off like she turned off the key. She’ll pull over to the side of the road, turn off the key, put it in park and it will start right back up. I’m going to have her bring it to Topeka so I can take it to my favorite Jeep dealership and have them look at it. My fear is that with no check engine light and no codes, they will likely just say we don’t know what it is. It almost has to be electric. I had something similar to this happen to me on a Jeep grand Cherokee many years ago. I put in a new battery because the battery was about six years old, and it never happened again. That could have just been a That could have just been a coincidence. Any ideas?
A good tech with the right scanner should find the problem even if it not throwing a code..
