Welcome to the forum Randy,

Have you cleaned everything up from coolers to the hydro unit's case?
If not that is where I would start.

I have cleaned everything, changed the hyd oil with JD oil and new filter, Unit works fine when cold (2 hrs) gets slugish when gets warmed up and really falls on it face when it gets hot.
