Almost always the fuel filters. If the filters have been changed and the air is removed from fuel system it may be the pump. There should be a primer bulb in line with the fuel hose coming from the tank. Give that a squeeze and it should get hard if you have fuel pressure. If the primer bulb collapses when the machine dies that means there is something inside the suction tube located inside the tank. I have had this happen many times. You have to remove the suction tube from the tank to clean it out. DO NOT BLOW AIR INTO THE LINE. Good luck.
SOURCE: bobcat 753 skidsteer right drive control is jerky
check and, clean the hydrolic directional combination valve screens; dirt in the lines causes this

Depends on serial #. Should be in the engine compartment right side lower next too bottom door hinge in plastic covers two of them you will see the wiring harness going into the back of them. Relays are above battery.

SOURCE: How do I replace hydraulic line from pump to right arm on my 96 753 bobcat
to replace hoses on hydraulic equipment you have to have all the parts in the relaxed position clean the area of the connections so that dirt will not get into the system.
that is the bucket on the ground, allowed to tilt forward
nothing can be held under hydraulic pressure
the engine should be shut off
use spanners to undo hose fittings (no hands)
ensure a safe work procedure and wear rubber gloves , eye ware ,face shield and keep hands away from connections ---oil under pressure can penetrate the skin and cause immediate death ---
once you have the hose disconnected replace it with a new hose
after fitting the new hose and tightening the fittings ,start the engine and cycle the hydraulics as this eliminates the air in the system
