Time to start isolating and testing components. Start by doing a pressure test to make sure the pump is producing pressure. Make sure the loader bucket is heavily loaded or chained down when you run the test.
If the pump is making pressure disconnect the hose going to the lift cylinders and insert it into the filler on the loader reservoir. Start the tractor and operate the loader valve to "raise" the loader. Do you get an immediate garden hose type flow into the reservoir?
If you do the problem is in the cylinders.
If not the problem is insufficient flow upstream from the cylinder - e.g. pump or control valve. Repeat the test with the supply hose to the valve to see if it's the valve or the pump. If the flow to the valve is good then it's a pump problem - worn out pump or restricted supply from the reservoir.
