2024 RTV520 Hesitation, Misfire and sputtering - Need advise

[omextreme]

Bought a fire damaged (body only) 24 RTV520 and just got it running - Sort of..- Needing advise on next steps.

Unit fires right up and idles smooth.
between idle and 50-60% throttle it bogs, pops hesitates and all the not so good stuff most of the time.. every once and a while smooth acceleration bottom to top. Hot or cold same outcome.

Once it works past the slow zone it runs just fine, Drives at full speed smoothly.

I have verified the filter sock on the fuel pump is clean, Replaced the plugs and air filter.

Looking for next step advise.

First thing that comes to mind is fuel lines. Make sure they're not damaged, burned or collapsed.
If there's any fuel filters you haven't already replaced, check/replace those as well.

I didn't think to replace the fuel lines, at full speed it runs great... However after messing with this all day I have dropped it off at Kubota.. Lets see if $300 in diagnostics points to a cheap and easy fix..

I did verify fuel pressure and injector functionality.. But alas.. time is not abundant these next few weeks so I am paying the pros
