2019 Speed Triple Rs Cutting Out

My 2019 RS sometimes cuts out on downshifts when the throttle is closed. It happened every other ride when I bought it and the dealer (after arguing hard to do nothing) eventually changed the right switch cube. That seemed to cure it but 1000 miles later the gremlin is back. Has anyone else experienced this? I can electric start it back to life but not bump it for some strange reason which makes me think it must be an electrical or software issue

 

Good advice thanks. First time around I started filming every ride and that really helped to make the case. The dealer’s original response was to give the bike a 20 minute ride and say it was OK without any attempt to fault find. I’m going to film every ride from now. It’s still under warranty thank goodness

 

They’re all tight at full lock but the cut out happens in a straight line just as you roll off the power to downshift
