Maybe the Hydro Boost? Thats just from personal experience with my tow trucks. When the HB (hydroboost) goes bad it puts a strain on the powersteering pump, which in turn can sometimes shut down the motor at lower rpm. It has happened on my F450's, havent owned a Dmax until last week, so I cant say if it happens on these too. If the temps have dropped below freezing, then you may have some moisture in the power steering system and just need to replace the fluid. Dont take my word for it as I dont have any experience with the Dmax, but I thought I would throw it in just incase it would help.
