[QUOTE="thoughtbelt923, post: 132778, member: 23095"] Sounds like the brake in the left motor may be leaking excessively. You can do a case drain test which there is info out there online. Basically comparing the flow back from the drive motors to the case drain filters one side at a time. If you go that route, I'd also consider pulling the case drain filter and checking for debris. You can also compare the charge pressure at high idle after startup, then watch the drop after pressing the brake release/press to operate button. If you see a steep drop and it doesn't recover, that's another indicator of excessive leakage. If it's leaking too much, the charge pump inside your hydro-static pump won't be able to recover. It working fine after startup then not working later could be due to the hydraulic fluid warming up and becoming thinner which consequently makes leaks more pronounced. [/QUOTE]
