    Husqvarna RZ4623 shuts off after running with PTO engaged

    While mowing (PTO engaged) runs fine for a while (~10 minutes), but then engine shuts down. I let it sit for a while - then runs again, but then only for a couple of minutes. Seems to be related to PTO being engaged. Engine runs fine without PTO being on. Any ideas?

    Does the engine crank fast or slow ?
    A faulty alternator / rectifier can cause the voltage to drop so low that the carb solenoid cuts off the fuel supply.
    A foulty PTO clutch can draw more power than the alternator can supply with the same results.
