I’ve got a 2008 Bobcat A300 with 900 hrs and it starts right up runs for 5 minutes then pops up on screen saying hyd charge pressure shut down it starts right back up but will only run 5 minutes at a time I’ve changed filters sensors I can’t figure out what it is has anyone had this issue before and what was the fix I’m desperate it’s been setting in my shop for 2 years time to get it out of here ! Thanks in advance
