Hi my name is Robert....
It sounds to me that you are losing fuel prime in the system, all this would take is a loose filter, loose cracked fitting and you will suck air into the system and cause the engine to shut down. I might start off by replacing the filter(s) and pre-fill them with clean diesel and see what happens. This can be a difficult condition to chase down and might require a mobile tech. to come out and have a better look if the filters do not take care of the issue.
Sorry for the delay, your question was closed and I could not respond, had to have it re-opened so I could respond.
Really sounds like you are sucking air, do you happen to have a manual prime pump near one of the fuel filters, I know from past experience if the seal in that primer pump fails it will suck air and cause the engine to shut down, have seen that on a few and the engine might shut down on you, you also would not have any codes. I deal mostly with Cummins but have worked on a few CAT'S.... IF you like I can put your question back up there is another expert that has more CAT engine experience then I do. He might have some input on this. Normally if the engine starts and runs then shuts down it could be a leak in the system and if a gauge is hooked up or sight glass you would see bubbles in the fuel while the engine is running...

I think I am going to put your question back up for that other CAT expert. I am not sure he is around at this very moment, experts come and go daily. I want you to have the best answer and he might have some more input on this.... Robert
The only other thing I would check is the chassis battery voltage, make sure it is not dropping off when the engine is shutting down, the electronics are very sensitive to low voltage, make sure no cables are resting on the frame, have seen that before where a cable will rub and cause the engine to shut down probably not the issue but I would make sure it is not voltage related.
I am going to step out of this question. I do not know when another expert will respond and went into this question blind as I did not know the exact issue OR what has been checked out. Most experts come and go and your question will be available for others to view.
