Not My Field  
OK, it's time to play "Who Knows Anything About Small Engines?"

So, the mower here. A few years old, a Toro, i believe. Not kept in the best shape, but more than capable. Been using it every weekend for months. Oil is full, gas is full. Last weekend, pulled it out to mow, it started up, ran for a few minutes then conked out. Starting it up again results in it firing just fine and then dying again almost immediately, and this is repeated until i get annoyed and quit. Gave it a day of rest, tried again, same story: ran for a few minutes, died, each start since is start and die. This weekend, same thing. Replaced the air filter (thought maybe a lack of airflow was the culprit) only to have it do nothing different.

Right. Engines are not my thing. I understand how they work, but know nothing about repair and troubleshooting. Anyone with any knowledge care to take a stab at this?

See if there's any way to flush the fuel line(s) through, preferably back towards the tank. There may be some crud in the tank and/or line(s) which is initially settled so the engine runs fine but the flow of fuel drags the gunk up into the lines where it can restrict or block the flow and stall the engine.

I've worked on cars on and off at home for the last ten years or so and that's my guess. I had an old diesel Land Rover Discovery, which would start and run fine but whenever the fuel flow was increased by pulling away from standing or hard acceleration it would choke and stall, almost killing me at junctions several times. Some bacteria got into the sedimenter (a coke-can sized pot in the fuel line between the tank and engine/pump) and formed a really manky disc of crap at the bottom of the can like a solid pineapple ring. When the flow rate of fuel would increase the disc of crap would get sucked to the top of the sedimenter where it would block the fuel in and out pipes. It was some vomworthy crap to handle even with latex gloves on, I tell you.

Replied to the original FB message. Anyway, yes, he's sitting here on my desk, staring back at me. I have a feeling he'll hold my dice and live inside the esoteric dicebox, waiting for the right moment to spread madness and random rolls.
