Just a thought, My 2013 F700GS went through a phase of just stalling or running really rough when it felt like it. I had changed the plugs and used different garages for fuel but the symptoms still occurred. I just had the ring antenna on the ignition barrel replaced as EWS was displayed on the screen and the bike would not start. Perhaps your antenna is on the way out and when it feels like it, not reading the chip on your ignition key and activating the immobilizer for a moment ?.
