Engine cut out

[Jacob 'Berg]

We were riding back to staging area after 4-5 hour ride yesterday on dirt road. Throttle position pretty constant at 1/2-3/4 throttle for about 15 minutes. The engine started to cut out and I thought I had run out of gas, so I immediately hit the kill switch and stopped. Still had gas in the tank. Started fine, ran fine the last minute or two it took to get back to the trucks.

Is it possible this was a partial/incomplete seizure of the piston? I may be borderline lean on the main circuit, but the bike did not run hot at all during the ride, which included a lot of 5th and 6th gear sand wash connectors.

Bike is starting and idling fine. Any input on whether I should take a look at the piston and cylinder, or if I am being paranoid, is much appreciated.
