I replaced fuel pump, line, and filters... still has the same issue

The diesel I get I make sure I get from a shell station that constantly had trucks going through it. So they pump a high volume of diesel. But I'll drain tank and replace both filters again.

The entire fuel line is rubber. Would the fuel line constrict or dialate as it heats up? And if so, I'd imagine it would be after going through hot fuel pump?

I've unscrewed cap and held slightly above while running and it still has issues. I've also disconnected all fuel lines from injectors and purged any air in lines. I've had two kubota mechanics from different dealers tell me not to bring it to them and to keep trouble shooting myself.

It seems like an overheating problem, but I can't find anything overheating. If there something that could trigger a fake overheating response from engine?

I put seafoam in with the last tank to try to clean lines. So far hasn't had any effect. I looked at flow through side of fuel filter and level stays the same while running.

It currently has 711hrs

After mowing for 20 min, my zd18 will bog itself down to an idle. If I let it sit for 30 min I'll get another 20 out of it. I replaced fuel filters, air filter, all new oil and hydrolic fluids (including gear box), new battery, removed and cleaned tank, replaced fuses, radiator screen is clear...
