MC21 R7L with M parts "wire splice" Std engine, pipes, ignition, air filter.

This is the 2nd time this has happened, 1st time on a track day, now on the road.

easy ride for 40 miles or so then holding about 11K for about 4 miles then up to 11,500 then nothing. The engine cuts out completely dead. I slow down bd let the clutch out, and it fires back into life, but only on 1 cylinder and no its hasn't seized.

Ride home last 2 miles running on 1, remove the front plug and yes it's all oiled up

The side stand faintly lit (with the stand up and glowing properly with the stand down.

On the track day the bike ran for 3x20 min sessions before the same thing happened.

Any suggestions , apart from don't ride for more than 50 mins ??
