Toro Rear Bagger 21 stalling - primer problem?

Hi there - I'm trying to fix my own problem - I bought a used mower last summer and it hasn't given me any trouble until now. I fired it up today and although it started fine, it stalls out after a few minutes. I restart it, and it stalls sooner - then sooner, then sooner, until finally it won't start.

Plenty of oil - plenty of gas - I did notice that when I pump the primer it feels and sounds like it's bringing a lot of air in with the gas. Usually when I pump the primer I expect to feel a lot of liquid (gas) moving through however it definitely feels like there's a lot of air getting in there.

I checked for obstructions between the gas tank and tube - found nothing.

Does the fuel filter sit below the primer? It looks like the fuel line runs into a cylinder (which I'm assuming is the fuel filter) and then the primer squirts fuel up into a chamber.

I also checked the spark plug - it's not dirty and seems to spark fine.

Any ideas?
