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?

13.4 is still above 12 volts. When I’m running my whips, light bar and high beams on my 1000 my volt meter is around 13.8. I don’t think thats your problem. 14+/- when nothing is on and at idle. Check your ground connections.

I would check both terminals on the battery and ground connections. While you’re under the seat near the battery, check the plug in connections to the PCM too. 😉 Post an update when you solve it. 😎

My ‘17 is in the shop right now for the 2nd time in as many months for the same exact thing. Runs great until it doesn’t. Shuts off like someone turns the key off when shifting from 1st to 2nd or 9-10 mph. Which ever comes first. Starts right up each time. First time in the shop they couldn’t replicate it. Tech said a loose connection was found, cleaned and reset. Took it out today, after 20 miles or so, it started dying again. Again limped it home starting and dying all the way back. This will be the last time I trailer this pos. As soon as it’s out of the shop I will be trading it for a can am. I cannot afford to be stranded in the remote country I hunt in. Not only inconvenient but could be dangerous.

I wonder if this is a symptom of the fuel pump recall/upgrade. Sure sounds like it.
I'd have all the updates performed first.

I don’t think this applies to mine. Mines a ‘17 and when it dies it will fire right back up as soon as it stops rolling. It idles perfect and then dies again as you start rolling again.

So I believe I have found what my issue was: I was using a wiring harness that plugged into the test port. I removed this and bought a "Plug and Play" harness that attaches to the cigarette lighter harness. Since I did this, I haven't had any problems.

The diagnostic connector under the hood?

My problem is a little different. I was driving down the road and all at once the machine started running rough and would only run 10 to 15 mph made it home and now acts like it is starting up against a lot of compression and won idle.

Got the call from the dealership yesterday. They are sending the case to Honda for advice as they cannot find anything wrong. No codes are being thrown, unable to replicate etc, etc..
