Default XB12s cuts out at steady speed

Hello, We bought an 07 XB12stt. While riding at steady speed it will Cough. Revs up fine doesn't die any. Just cuts out just enough to be aggravating. No motor indication lights on. Ran several fuel injector cleaner.
Replaced plugs and cleaned air sensor in air box. Done the TPS throttle reset throttle 3x twist with ignition on motor off. Any ideas? Thanks

If you are using spark plugs with the screw-on ferrule on top, check to see if it has unscrewed inside the ignition wire cap. I have had this happen to me, it results in the engine cutting out intermittently. Something to check, a starting point if you will.

The plugs tips are good. I feel like it's an air/fuel issue??
