My 2018 M6060 with a only 90 hrs is currently doing the same thing. Runs normal until it gets to operating temp then it can't maintain 540 and will almost stall if I lift loader or while turning while pto engaged. Been looking online and seen its a common issue as you stated with the psb recall out.

I’m having same issue at 300 hours. First thought was starving for fuel and possibly had plugged fuel filter so I changed it the next morning and tractor seemed to be ok for about 45 mins of brush hogging then it lost power again. Found your video and took tractor to dealer. Two weeks at the shop they tell me they can’t recreate the issue which I told them it would need to warm up and be under a load. Their suggestion was a fuel system flush I ask if there was any evidence of contamination…. “No” so I reminded them of the injector issues so I’m waiting on service writer to talk to service manager who is out of the office this week. Long story to ask if you if you notice the power loss only after t warmed up then be ok when first run tractor after it cooled down? Thanks

It’s injectors.. they can tell when they plug it in..

@@RockyRohdeSounds like your service department knows a bit more than mine. They told me they had to pull them and send off to check them.
