The other evening I was driving some country roads and on three different occasions my machine died on me without any warning. No bucking, no surging, etc? Like it lost its electrical power. I didn't notice any warnings or error messages on the display. Each time I turned the key on and it started right up. Only one instance did I feel like it was lagging for power for just a second. I have put in plug into the accessory port on the wiring harness and have a 18" LED light and a soundbar hooked up to that. At the time it died, both of these were on. I noticed my voltage meter was reading around 13.4: could this be the culprit?
