John Deer D105 acts like starving for fuel

[PLX]

Hello, 1st time post. I have a JD D105 lawn tractor that acts like it's starving for fuel after running for 20min.

The 1st 20 min or so it runs fine. Not sure what's happening after that.

I changed the fuel pump thinking that was the issue but no change. Plug is new, air filter cleaned.

I did notice that the fuel filter occasionally has air bumbles flowing thru it. I lifted the hood & ran at high speed to chk this.

Any thoughts would be appreaciated.

Can be dirt & debris in the fuel tank
Cracked or broken fuel pick up in the tank
Blocked tank vent ( loosen the fillercap to cheack )
Deterioated fuel lines
This assumes the fuel pump is good .

Fuel pump & spark plug were replaced 1st with OEM part. I will chk all those suggestions.

Thank you!

And if it is anything like the last JD I did here with fuel issues the fuel line will have an inner liner that can come loose and collapse causing fuel delivery issues.

Is. There a trick to getting the fuel line out of the tank?
