Have Ford Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.
Do you run a power programmer on your truck?
Will your scan tool show the ICP pressure while cranking?
Does it smoke during this power loss?
This looks to be a weak high pressure oil pump or internal leak at the oil rail under the valve cover or there is a concern with the oil bleeding down out of the high pressure oil reservoir. Prior to starting, remove the oil pressure sensor from the reservoir on the top front center of the engine. If the oil is more than an inch below the sensor, then your high pressure oil pump should be replaced.
