This mower only has 200 hrs on it. Occasionally while mowing after 20-30 minutes it starts running rough and wants to die and sometimes does. After it cools down it starts up and runs fine for awhile. Carb has been cleaned twice. It's not the vent hole on the gas cap. I'm thinking coil maybe? It's a very twin engine.

Could be that the fuel line is constricted. You need to test the fuel flow and the spark when it dies. Good Luck, Rick

:iagree:   Takes 4 things to make an engine run.  Compression, air, fuel and spark.  It was running OK and runs after it cools so compression is there.  Make sure your air cleaner is not full of dirt, dust, etc. so it can bet air through it.

Yah already have checked air filter. I'm still thinking coil going bad?

My experience has been when the coil goes bad it just quits, maybe it's just me. My advice would be to immediately check for spark, don't wait until it cools down. Weak spark would indicate coil condition. Make sure there are no restrictions on the fuel line or filter as advise above.
