Losing hydraulic pressure with no leak

I have a Clark c500 30 type g forklift
235 36 3855. It is losing hydraulic pressure after lifting the the boom whether it's lifted a foot or all the way up. The oil lever is correct and I have no hydraulic leaks anywhere. Is there a back flow preventer somewhere that might be allowing the oil to leak back into the reservoir?
