Curtis B. :

With hydraulics still working, the drive shaft from engine to transmission is turning? That would leave the transmission declutch valve. When you step on brake, it kicks transmission into neutral, if valve sticks, you loose drive.,

Curtis B. :

Check declutch valve on the transmission cover.
