2003 honda foreman "dead in the water"

so as a little back story, I came home from school and like most days i wanted to ride so i started my ttr-250 and started my dads '03 foreman let it warm up and i went out in 15 mins and the thing had died (it was cold i diddnt think anything of it) so i tried to start it up and it just wouldnt start and hasnt started to this day i try the push button and nothing and the pull rope just reveals some knocking inside the engine any help appreciated (also first post)
