5288 international hydraulic problems

[Mofarmer2000]

I have a 5288 international hydraulics levers work until there pushed to far backwards or forwards then turn off. Have to turn tractor off then back on to get to work again until it happens again 3 point works until I hit a hydraulic lever. I’ve checked the priority valve looked good. I have had all the valve boxes off under the cab. Have checked compensator block everything was good there. Any info on what else to check or look for would be appreciated
