Thanks for the update Tod. Check inside the hydraulic filters for signs of fine metal that looks like metallic glitter indicating a pump or component problem occurring. If clean, remove and inspect the relief valve cartridges in the main control valve for debris or damaged o rings causing them to bypass pressure or stick. If this all check out okay the next step is to have the pressures checked and verified they are in OEM specs to isolate a potential pump or valve problem. Let me know and I hope you have a great long weekend Tod!
