Hi my name is***** will be glad to try to help. Check the hydraulic filter and oil for signs of metal/debris indicating an internal component failure occurring. If ok then inspect the control valve and relief valve cartridges for metal/debris,damage/damaged o rings, and sticking. If ok and there is good pressure to the drive motor, check for excessive case drain pressure at the drive motor indicating a faulty drive motor. there should be a low volume of oil from the case drain port on the drive motor with travel engaged but against a loading gick etc to prevent movement and a hose run into a bucket.Let me know
