2013 Honda Recon ES - engine shuts off while driving. Went to Honda Service and they were not able to replicate, so they did nothing. Any ideas?

 

Does it do it regularly? Does it do it after you have been using it a certain length of time? Can you re-start right away, or need to let it stand for a while? Usual suspects are tank vent blocked, a sucking sound if you open the cap when the fault is on, indicates this. Over rich mixture, indicated by a sooty plug, check after a run. Or an ignition fault, try another plug first but usually trigger or power coil failing when hot. Carry a spare plug, when fault comes on, whip cap off and try for a spark with spare plug against head while fault is on.

 

This happened on a ride a few weeks ago. Several day before the ride, I changed the spark plug just as normal maintenance. During the ride the shutdown occurred 3 times, all while traveling approx. 40 mph. The atv would start back up after waiting 2 or 3 minutes with no problem. I am not sure if it showed a fault as my son was driving it. Thanks for your response!

 

Try another plug, new does not always mean good. 40mph on a Recon must be close to flat out, it is possible he seized it. They quite often run after they cool a bit but you usually get a lot of piston slap and compression will drop.
