Re: 450C that runs for a little bit and loses power then dies?
How do you remove the filter screen going into the injector pump? I'm having the same problem with my 450C crawler loader. Engine starts fine, runs for a few minutes, then dies. I have removed and cleaned the fuel tank, replaced the screen filter in the base of the tank, cleaned the fuel tank vent line, and replaced the fuel filter. I'm stumped.
Thanks in advance for any help.

Have you checked to see that the return line to the tank is clear? That includes removing the check valve fitting from the injection pump and seeing if it has foreign material looking like mouse turds in it. You can remove the timing window cover and check for debris there as well. If you find that condition, it is the Pellethane ring in the pump breaking up and you are looking at a pump rebuild.
The screen in the pump inlet is under the inlet fitting.

I have not checked the return line. Will do that next.Sorry, I don't know much about injection pumps. Is the check valve on the pump return line? Thanks for the help.

The check valve should be the fitting where the return line connects to the injection pump.
