My dozer cranks & idles fine, but when i run it for a little while, it looses power and idles down, sputters, and sometimes dies but will crank right back up usually. It will run a few minutes fine and then do it again. Im getting no codes. Ive changed the main filter, & I cleaned the filter in the back that comes from the tank(the screen inside had a lot of trash in it) but it did not help. Any ideas on what I can do before I have to call a mechanic to come look at it?
There likely is a screen in a banjo bolt on the suction side of the hand priming pump.
