Welcome to TBN
I suggest to check system pressure which should be 2275 psi. How long since hyd filter was changed?

Check your fluid level.

It could be fluid flow, volume, or pressure as suggested. If all else fails you could have internal bypass leakage in one or both lift cylinders.

Does it sound like tractor is straining while attempting to raise the loader. I.e. similar sound like when curl cylinders hit end of travel
if yes you potentially have a quick disconnect failing which is restricting flow one one of lift circuit lines.

Any resolution to this?
Broadly speaking (if you've established that you have correct pressure), then either there is a leak, in which case the cylinder won't move but the hydraulic pump will not labor or go into pressure relief. Or there is a blockage, like oldnslo says, in which case the cylinder won't move but you'll hear the pump laboring and the pressure relief valve hissing. I've experienced blockage on my lift circuit's "down" direction.
