Dead Stroke Returns
I was turning a corner at a red light today, when straitening out with a 7000lb. Cat on the trailer I was pulling and my 05 power stroke, which has been in the shop three times already, (New transmission with 300 miles-bad planitary gear) stalled on me. I was dead on the road with the engine not even coming close to cranking. Supposably the mechanic can not find a code and is keeping my truck in the shop over the weekend to try and find it Monday, never mind I that I was trying to leave for Co. for a elk trip today. Mechanic told me he thinks that there must be an internal oil leak, because a sensor is dry up top. Any Suggestions?

The most likely sensor to be "dry" within the oil system is the ICP (Injection Control Pressure) sensor. By the term "dry", I assume the mechanic means that the sensor is seeing no pressure- this is the foremost telltale sign of a interal high pressure oil system failure; and from your description of what happened, this is the most certain culprit.
What we have been seeing most of lately, in terms of HPO system issues, has been the open failure of the IPR (Injection Pressure Regulator). When the regulator fails open, about 80% of the overall hydraulic rail pressure is lost, and the system can no longer build enough pressure to properly fire the injectors.
IMO, a simple failure of the IPR, or the high pressure pump, is more likely than an interal leak. An interal leak, generally, is localized to one side of the engine or the other- most of the time, the failure will result from a split o-ring seal on the high pressure stand pipe (the portion that transports the high pressure oil from the HPOP to the oil rails on top of the cylinder head). Normally, if this occurs, the system can still build enough pressure in the opposite engine bank to keep 4 cylinders running (and yes, the truck will run on 4 cylinders...actually 3
). If this happens, your interal leak will turn into a MASSIVE external leak in a real hurry...

A gasser tech or parts changer can turn a 5 min fix into a buyback. Let us know what happens. I'll be thinking about other possibilities. I do have one question though. Did it ever sputter, or surge or anything of the sort prior? Or did it just stop?
