Checked both fuses, OK. Starter just spins engine with no firing.
Check for spark is the wire on the spark plug is the plug good check for fuel flow possible electrical short
Blades are probably still engaged or the arms aren't parked or you're not in the seat

Sometimes, the main jet to these small-engine carburetors gets clogged up. It is easy to get to. It is the brass bolt that holds the float bowl onto the carburetor body. If you remove it, gas will readily flow out, so drain the fuel by removing the fuel line and placing it into a suitable container first. Remove the bolt and exterior washer (don't lose that). Clean the bottom hole in the bolt and pay close attention to the very small holes in the smooth section near the top. Use NO metal objects to clean the orifices as they are a precision size and can't be enlarged or scraped up. Clean the float bowl also while it is off, make sure the bolt is clean and shiny and reinstall. This will assure the carb is getting fuel, providing there is no clog between the fuel tank and the carb body in the fuel line. You should pull it and blow it out, making sure it is clear also. I recommend installing an inline fuel filter on ALL 4 stroke machinery.

One suggestion wouild be to check the spark right after failure. You can buy in-line spark indicators that give you a visual light if you are getting spark. This way you could see if you are losing spark when the engine warms up. If your spark is good, you would want to check the compression after the engine is warmed up and quits. You should have at least 100# minimum.

This sounds like the carb is plugged. Sometimes fuel thickens and makes globs...
If you verified the fuel flow to the inlet of the carb, then you need to take the carb off and open it up....
So, what needs to happen is you blow out all of the passageways with carb cleaner.
Any adjustable jets: make note of the position it is in, and FINGER TIGHT turn it clockwise until it closes (typically 1 to 1 1/2 turns) SOOOOO, you can set this jet back to the same positon....when finished blowing everything out, bottom the jet and back out the number of turns out, noted for that jet.
Open the float chamber, and clean as necessary, Inspect the float adjustment: invert the carb, and observe the angle of the float, relative to the carb body.... Usually almost parallel, but not necessarily.
Inspect the inlet valve, and clean those areas...
I usually use all new gaskets and valves, but if you are not a carb person, cleaning is effective and I think old gaskets may be okay, if not torn or damaged.

I had the same problem with my Toro z4200. So far I have replaced the fuel filter, fuel pump, removed and cleaned carb, replaced carb solenoid, and squirted 5 cc gas in the cylinder. Starter turns at normal speed but engine will not crank. Replaced plug, pulled plug from cylinder and getting blue spark. Replaced fuses. Still will not crank. Cleaned battery terminals , all electrical contacts. Will not crank. Checked SP switches in steering levers and seat with ohmeter, they seem to be opening when button is depressed. Pulled flywheel cover to check pin. It is not sheared or even slightly displaced. Have ordered new diode and really switch. If these don't get it to crank, I am stumped.
