stock sj bogging a few second after sitting like 10-20 minutes

hi all, just bought a used stock 2016 sj. it runs so good and so much fun to ride everything works well except when I parked the ski to rest for like 15-20 minutes then when I started the ski and if I touched the throttle lever the ski will die. So what I did was that I had to let it idle without touching the lever for a few seconds like 5 seconds then I could start to rev it slowly a few more sec then the ski came to life and ran so good without any problem untill I parked it again and it will do the same.
I sit the leaking needle and seat? old spark plugs?
