If you haven’t already changed the fuel filter, I’ve seen a semi plugged filter cause that same problem.

Export threadMy Gravely Z260 did the same thing. It would only run 15 minutes and die. It was the fuel filter causing it. Chased it for a week thinking it was a week fuel pump but in the end the filter cleared it up.
Engine Options: Kawasaki, Kohler & Briggs...never offered with a Yamaha.Does it have a Yamaha engine on it? If so, get rid of it.
Like being a parts cannon, eh? Isolate then buy. Don't just throw crap at it till you know what it is....Ok, so it's not the gas cap. I tried to cut the lawn today and sure enough, 15 mins into it, it started to sputter. I immediately open the gas cap and it made no difference. It still quit. I got my inline spark tester and I got sparks. But maybe by the time I got my tester from my garage and walk back to my mower, it must have been about 5 mins. Maybe enough time for spark coil to cool down??
I'm going to order 2 new spark coils, spark plugs, a fuel filter, and a fuel pump. Easy enough to change the pump and filter so if those are the culprits, I'll return the spark coils. Amazon Prime cost me nothing to return them anyway.
