My B7610 has an issue where it will stall out randomly. I have noticed that the fuel water separator bowl will start to run dry and then the tractor will starve for fuel and stall. I have changed the fuel and the separator bowl and filter. Fuel flows from hose from tank to separator no issue. This is still happening randomly. Any thoughts or suggestions. Tried to pinch the small hose that runs off of the separator no change. Removed fuel cap no change.
