Which part doing a problem?

[Bravo45]

I have two 2010's T300 cat and one of them is doing misbehaviour from some days.
Problem is that when it's engine starting, it work well but after 10 mints, it going to shut down with misfire.
I'm tiring to it but fail.
Have any idea which part making problem?

Sounds like it could be a fuel problem, the first thing I would do is change the fuel filters.

I agree on changing fuel filters. Also check amount of fuel flow from the tank.
