I bought a gas Kubota T 2380 used. It will make about 4 passes on the lawn, then it starts dying from lack of gas. I have replaced all fuel lines with 1/4 inch line replace the fuel pump twice and the vacuum tube on fuel pump. It will run after it cools down. Anybody know what's wrong?
Start by loosening the fuel cap.
If the problem goes away then the tank venting system is not working.
IF it makes no difference then if you can get at it, drain the fuel tank & remove it
Wash out the tank paying close attention to the outlet which can get plugged with debris that you will scratch a bald spot on your noggen wondering how it got in there
