Stu Ungar - how many WSOPs did he play in?

I'm not sure if this post belongs in this forum but forgive me if it doesn't...

Anyhow, I just finished watching the movie 'High Roller' based on Stuey's life and I was wondering how many WSOP's he entered? I know that he won 2 back to back, basically the 1st and 2nd time he ever played in the WSOP and he won the 3rd time in '97. However, did he just disappear for a while after the 2nd time and finally showed up again in '97 or did he play in some of the WSOP's in between but got knocked out or whatever?

I'm only referring to the main event.
