Alright i have a 2011 trx420fm. It rides great for the first 10-15 minutes then suddenly sputters and dies. Its hard to start after and usually have to wait about 5 minutes before it will finally fire. Ive checked air filter and fuel pump and filter. Is there anything im missing? Also i noticed tonite that after it stalls i turn the key on and there is a slight ticking sound near the rear of the motor.

I'm not familiar with your model. Does it have a fuel tank vent on it that could have gotten plugged up? Does it have a Bank Angle Sensor on the motor? Either of those could be suspects if your bike has them.

Welcome to the forums!

Thank you. Sorry i meant trx420fpm. Its a 420 rancher. I dont know if it has the angle sensor on it to be honest. It does have the fuel tank vent and it is clear. When i ride it i ride it fairly hard and have no problems with it. I let my daughter run it yesterday and thats when it started. She was just driving it around the yard. I did find the positive battery cable loose so itightened it up but it still stalled out after 5 minutes of her riding it

If you found a loose positive cable maybe there are others loose? Check grounds on the frame and the motor. If it gets ridden in water check for moisture in all the connectors in the wiring harness. Other than those basics I don't have any help... I would probably study the service manual and start testing things... fuel pressure, ignition coil, wherever the FSM led me.

In case you need a copy of the FSM it is HERE.

Hopefully someone more familiar with your machine will chime in and help.

If your fuel tank vent is clear I would say your fuel filter is dirty and clogged. Replace that.

Ok thank you for the FSM. I appreciate the help
