I get the same problem on mine if I really get into it. I comes back with a code saying my IPC pressure is above/below desired.

 

Could be a code for low high pressure oil pump

 

x2 on the low pressure from the HPOP.

 

Yep Id say thats your HPOP not being able to keep up, its not uncommon

 

all that means is that the computer is sensing higher then acceptable pressure levels so its cutting the truck off. there isnt really a way to stop this i'v tried
