Sounds like trash in the fuel tank and/or line running from the tank to the fuel filter. Check for vent line blocks too. You would be surprised what mud daubers can do.I rigged up a small fuel tank with some odds and ends around the house:
16oz vitamin bottle, some spare fuel line and shutoff valve, couple hose clamps and a metal valve stem.
I successfully ran three 'tanks' down without any stalling issues, about 40 minutes total. Time to see what's going on with the fuel system.

No, the only issue I saw with it was the rubber bushing that holds it in the tank, that was cracked and not holding it firmly. That's on order from Amazon.Did you change out the pickup line?
With the age on those lines, I would replace all of them. It’s cheap enough.Update: Fresh gas, new bushing, new fuel lines and it seemed to run well (not being too hopeful). It did hiccup once but that was it. It doesn't run well at low throttle so there may still be some gremlins...need to look at fuel pump line from crankcase to see if it has any cracks. My fuel transfer test didn't show any issues, it moved about a quart of gas in under 2 minutes which seems more than ample. My testing with the hillbilly setup shows it uses about a pint every 15 minutes, or 1 gallon per hour.
I have the same mower. Since it did not come with a fuel filter I added an in-line filter.I have a Toro TimeCutterZ with a FR651V engine. (circa 2010). This season it has been plagued with stalling issues. When cold it will fire right up with choke out, push in and runs smooth. At times it may run for 15-20 minutes before it dies. It will usually restart just fine but will die quickly with light load on engine (PTO on/off, driving). Sometimes pulling the choke will keep it running, but no power. It seems to get caught in cycle of revving/bogging, you can see the governor opening/closing the carb.
I have replaced Plugs, Coils, Fuel Pump, Carburetor, Fuel Filter. At this point I'm at a loss. Plugs do get a little dirty, but I think that's due to the stalling issue and not the cause. I checked the valve lash and was a little out on one cylinder (exhaust), adjusted and no difference.
Digging around on this forum I may try the 'alternate' fuel tank option to rule out any funny business there.

I had same thing happening . finally figured out that I was tightening gas cap ( 3" diameter) down too tight and it must be causing a vacuum situation . All I had to do was leave cap backed off tight and problem has stoppedI have a Toro TimeCutterZ with a FR651V engine. (circa 2010). This season it has been plagued with stalling issues.

Check the fuel shutoff solenoid on the bottom of the carb. It might be going bad and it will shut off the fuel.I have a Toro TimeCutterZ with a FR651V engine. (circa 2010).
