Automatic Transmission Control Module problems of the 2011 Honda Pilot

My 18 year old daughter was driving home 6/28/19 at midnight. Car died while driving. Coasted to side of road. Restarted and drove some. Same thing. Many lights came on. Coasted to side of highway. Tried one more time and made it home. Miles on odo: 118,279. The next morning I started the CA and tried to drive to dealership. After 3 miles, the same happened to me. I was able to pull over and had aaa tow it 5 miles to dealership. At dealership, the said many error codes came up but they recommended replacing the powertrain control module (pcm). I pd $1,410. 16 to do this on July 2. I picked the car up and drove less than a mile and the same thing happened. I was able to start it again and then it happened as I coasted back to the dealership. They analyzed the car, talked with hq Honda reps and they recommended checking the spark plugs. They did and all 6 were bad. However, they were just replaced at 102,42 miles about 1 year earlier. July 9. I decided to replace the spark plugs and the dealership to their credit only charged me $200 (cost of labor). I was hesitant to replace them as I was not certain they had identified the true problem. I was shocked after spending the $1,400 that it happened again. Ever since then I am wondering if this will happen again. I am also concerned because this problem of the car just shutting down is extremely dangerous, especially if you find yourself on the highway. So I would like someone to look into this and to see if this has happened to anyone else. Thanks.
