Engine Scag turf tiger shuits off after about 5 to 10 minutes. Starts right back up

[hutch1917]

I have a Scag model STT61-25ch Ser #4310274. Starts up and runs fine for 5 to ten minutes. Sometimes will shut off again in about 30 sec Sometimes will run longer.
It will do this whether your on it or not. Deck on or off. I've replaced fuel filter and fuel lines. Any ideas?

Find the tag on the engine and find the spec number, it will help. Thanks.

Tag is pretty worn. Model # is CH25S/ Family SKH725U1G2RA SER # 2829418121/SPEC#68613

Fuel solenoid on the carb failing possibly. For a 98 model how many hours does it have on the engine.

Yah, you have SmartSpark, which is real squirrelly. So the easiest,first thing to look at, is look at the back of your keyswitch, where the wires plug on, and look for corrosion.

No corrosion, allot of grease, I suppose its to keep contacts clean
