What is the model number of this sellick?
Ok I will look and see if I have a manual you might want to check your fuel shutoff solenoid sounds like when it warms up its not holding the rack in the injection pump all the way
What kind of engine does it have?
I would start with the fuel filter inspect it and inspect the fuel filter housing for cracks may be sucking air after engine is warmed up
