My 2010 NT700V has developed a problem when hot, if you let the revs drop below about 3000 then the engine will quite often cut out and die, if I keep the revs above 3000 then it seems to run OK.
The MIL light does not come on when this happens.
I'm thinking the crank sensor might be failing??
 
Cheap and easy first ports of call are the spark plug caps (change to NGK) and also all the wiring connections in the area of the ECU (clean and reattach). Could also be the crank position sensor as you suggest but this is often accompanied by erratic starting as well. Do one thing at a time!! Happy hunting........
 
Tough one. Usually, ignition problems, unless having to do with mechanical advance, do not show up in this manner, ...if asking the bike if it has any codes stored isnt helpful, then I would just guess fuel. But I still wouldnt rule out ignition.
Certainly doesnt hurt to run the bike in a blacked out situation and look for arcing.
Does one plug look different than another?

I am no expert on spray patterns of old injectors. Maybe one has issues that are masked when the gas is flowing fast. Wild Arse guess.
