Power Steering Light On problems of the 2011 Chrysler Town & Country

While driving my vehicle on the highway at an estimated speed of 60 mph, for no reason at all, various warning/indicator lights started to flash (not all in unison) and the odometer speed indicator (digital numbers) went up & down as the car seemed to be stalling/missing. For a second it seemed to right itself then the engine completely shut down losing all power - electrical (all), power steering, power brakes, etc. And we were forced to coast to a stop in the breakdown lane. After waiting a few minutes I was able to start the car and it seemed that every thing was normal for the last 10 miles or so of my drive. This is the second time it has happened in the past 2-3 years which is a long period but alarming because both times were while driving on the highway. When it does happen you can't safely control the car once it shuts down - limited control at best. After the first time, I took it to the Chrysler dealer in kent OH (klaben) who services my vehicle because of the warranty and I trust them. They had a service technician and a manager both drive the van over the course of a few days (including highway travel) and couldn't duplicate the failure. Diagnosis was a possible computer glitch and since that diagnosis it hasn't happened again until tonight 2/10/16. It may be the computer but I will drive it tomorrow and see if it runs ok. If it does I probably won't take it back in (unless someone knows something) but I wanted to share the issue in the event anyone else has experienced the same problem. A computer glitch (if it is) is not like a reboot on the home computer. This failure both times has happened in light traffic. My fear is that in heavy traffic trying to pull over safely without any power and lights could lead to a major incident/accident. I should have my record of the (no) repair from klaben and they should also have in their data base.
