John Deere Walk Behind just died, now won't start.

Hi everybody. So I have an older John Deere Commercial Walk Behind, 38". It's been a great machine up until recently. I went to start it to let it run for 10 min or so. Well it ran fine for 10 min then suddenly shut off. Now it won't start. It's a pull cord, and every time I pull it the red fuel light come on so I believe it's getting fuel. I tried shooting a little starter fluid into the carb but nothing.

Anybody have any ideas? I'm kind of new to walk behinds (my second year)
