If its only when you attempt to curl, it sounds like an unseated or faulty quick disconnect

I agree with LD1 on this sounds like a quick disconnect failing. If you feather the joystick in an attempt to raise very slowly will the loader lift? Same with curl / dump. If it works at very low speeds this also points towards quick disconnects failing.

The quick disconnect are definitely seated correctly, do you think it is all four quick disconnects?

It's unlikely all have failed
Is this just curl or lift?
Their is two for each....and if a single one is faulty, it will cause that function not to work. Because they BOTH flow fluid when a function is operating. One allows fluid to supply the cylinder and the other allows return. Block either one (like a faulty coupling) and the system will deadhead

If both curl/ dump and lift / lower are failing is there a chance you have a hose crossed between the two functions? This would cause both functions to fail
when you attempt to raise does the loader lift a little then stop?
Do both of the hoses going to lift cylinders get stiff like under pressure?
