My Toro mower suddenly quit - thoughts?

I have a Toro Recycler about 9 or 10 years old. I've changed the oil in it maybe 5 times but haven't maintained it as well as I probably should. Last oil change and new spark plug was spring 2016. I saved the old spark plug because it still had some life in it. All season, it has taken about 3 pulls to get the engine running.

Yesterday I poured new gas into the tank and fired it up. Started normally (took 3 pulls) and ran for about 1 minute and then abruptly died. Was not making any unusual noise at the time. Now I can't get it to start. Doesn't even make noise when I pull the cord like it is trying to start. Blade is not obstructed and still rotates by hand.

My first thought was spark plug, so I put the old spark plug in from before the last tune up. No difference.

Thoughts? I don't want to put significant money into fixing up this mower because I planned to get a new one next season anyway (hence not bothering with the spring tune up this year). But if this is a cheap fix I'd gladly do that so I can get through the rest of the season and sell it for a little money next spring!

Does it have compression? Might just be some water that got poured in when you filled the tank before starting.

Doesn't really sound like it, because some air will usually get through eventually so that it will start again after a bit, but try loosening your gas cap. Sometimes they get dirty, not allowing it to vent, leaving you with a vacuum in the tank.

It died shortly after filling the tank and hasn't started since. Water in a carburetor doesn't dry out, it sits in the bowl. It's heavier than gas, so it stays there in the bottom, clogging the jet.

What engine does it have?
edit: (cheese posted while I was contemplating )
Dribble some fuel or a short squirt of starting fluid in the carb, if it fires then it is most likely fuel/carb related, if not and by chance it is OHV, pull the valve cover see if the rocker arms and pushrods are still in place.
