Welcome to the site !!
No I have not heard of that .... I am wondering by the sound you seem to be hearing , if it is not a fuel pump issue ??? , how many hours do you have on it ?? , and just to eliminate them , have you checked the valves ??
My first guess is going to be something related to the fuel pump or fuel , just because of the sound , as that is the only component that I can think of that actually would make a noise .... maybe the vent line to your gas cap is clogged ?? , that will cause a vapor lock and it will only die once you run it or ride for a bit and it pulls the air from the tank by the pump sucking gas , then it has no air left and will basically vacuum lock ..... Stator could be a issue , but I have not heard any issues with them .... I have over 62 hours on mine , and no issues at all ....
Try riding it and when it starts giving issues , loosen the gas cap (try and be on flat ground so you don't splash gas everywhere) and see if it picks up , that would tell you if it is a venting issue either from the line or the cap itself ..
Also , are you getting any codes flashing ??? (aside from the standard flashes that normally happen) ... , the only flashing you should have is the initial startup , whatever map you are in and if Traction Control is engaged , anything else would be a issue code
