My 2017 Yamaha has had that vapor lock issue since it was new. Fuel type seems to make no difference whether I put in ethanol free or not. It happens when the cart has been driven then sits for a while in the hot sun. Upon restart it does the put-put-put-put, as you describe and then that hesitation goes aways as it finally starts after a few seconds. Normal for these fuel injected Quietechs.
