Man I have been dealing with this on a 7.3 for the past day, and today I discovered the injectors and harness is the cause..... this is due to heat and wear in them.... only would do this after a bout an hour of running. But also look at the icp pressure. If it’s trying to maintain it, I would then start looking at your harness for your Injectors or the injectors itself..... too bad you cannot do a buzz test after it dies like I did to find this issue

What does the exhaust look like? What's the ICP and what's the fuel pressure?
the exhaust is clean no crazy smoking or change when it starts to die. icp pres is all norm and ill have to go back and look at fuel press. it does not have any throttle response when its going to die. have replaced fuel pump and ficm and two injectors. due to cylinder contribution test codes on number 1 and 5
