CAT 303.5CR shuts down with movement

[SaludaFleet]

We have a CAT 303.5D CR that had air in the fuel, after fixing that issue the machine will start and run normally but once it is put into any motion, including boom, the engine will stop. Any ideas or suggestions are greatly appreciated, thanks y'all.

Fuel filter was changed and bled properly?

Does it sputter to a stop or shut off like u turned the key off.??
Need more info to help..

Complete service on the machine, all filters changed, all air was bled out. It sputters to a stop. Engine idles just fine, but if you start working it at all the RPMs begin to fluctuate and then eventually it bogs down and quits.

Crap floating around in the fuel tank ? Rust or fuel bacteria . Or a bad fuel hose collapsing under suction?

U do know your not supposed to be operating any function AT IDLE..

When you changed fuel filter, did you ensure that Oring was still on top of water bowl?

And, if filter was changed and lots of debris was in bowl, could the lift pump filter be restricted?
