At 48k, under warranty, skip all the Internet BS Stuff and get it to the dealer ASAP and let them sort it out. It's Ford's issue now not us random folks on the Internet. It may or may not be anything in this thread and only someone looking at the truck will be able to figure it out. There are a million things that could cause low oil pressure and the symptoms you are experiencing.

Here is what has happened (Lewis is correct below, but your far beyond a fix at this point). The oil dilution has caused enough wear that the timing has jumped, and there is no longer enough oil pressure to keep the tensioners tight enough to prevent it. Your main bearings, cam bearings, and rod bearings as well as the crankshaft have significant wear in order for the oil pressure to drop that low. The timing cans rely on the oil pressure to maintain proper tension on the chains, and when enough engine wear from the oil dilution occurs, then the pump cannot maintain enough pressure to over come the additional clearance between bearings and crank. To the dealer. They should replace the engine. Now lets see after you visit the dealer if I was correct. (print this and show it to the tech/service writer). Good luck, and be insistent they take care of you!!
You are correct, only his has progressed far beyond a TSB fix. The damage is done.
KILOFINAL, what you experienced is the classic spark blow out when the rapid boost pushes accumulated water/oil/gunk mix in to the intake and creates spark blow out.

Pure speculation. Nobody can diagnosis that in-depth on the internet with such a vague post.
Turner Bosst ;Stop the fear mongering. I am really starting to take offense to you demigoding this engine and installing fear that the ecoboost is a poor engine. It is not, and the problems effect a very small population statistically speaking.
You have an economic interest to portray the engine in a very bad light, because your hopping that increases the sales of your catch can. The ford master tech at my local dealership says he sees very few trucks with the ecoboost come in for issues relating to the engine.
OP - Have a real tech diagnose your problems...not a biased internet fear mongerer...

Fear mongering or not the fact remains something wasn't right with the engine. I say wasn't cause the engine let loose today. It's being flatbedded to the dealership in the morning.
Spoke with my service advisor gave him the symptoms and he even said sounds like the engine is toast but will know more definitely when they look at it.

It would appear from the photos that the blocks are breaking at the motor mount areas on the 3.5L EB. That may be from cranks/rods breaking but the distortion is there and looks like torque helps it. Suspecting the aluminum block is not strong enough in these areas is easy to do. Believe all have broken in the same general area, blowing holes out and distortion in the mounting areas as that also is the main journal general areas internal configuration where cranks can't flex and rods break.
Notice the new 2.7L motor mounts do not mount to the side of the block but to the lower box the block sits down in/on top of. If this breaks it is just replace the lower box and not the engine block. My guess is the 3.5L EB line is going to rapidly close down in the future and the 2.7L family will arrive with several CC offers.
It is also easy to infer the breakage is not from normal driving habits but from extreme hard ( tractor pull ) type usage isn't being played with. LOL

And lets see if I am correct or wrong on my remote diagnosis. Do enough engine builds to judge pretty accurate.

Update
Got my MKS back this past Tues and after all the speculation and "fear mongering", it turned out to be just the turbo went south. The tech said the shaft let loose and cause the no turbo issue. The fact that the 3.5 ran fine w/o boost and there was no rattling, pinging or any other noise associated with a bad engine, that I shouldn't have any concern with the engine.
I will monitor it for awhile and go from there.
Thanks to Ford Service aka Crystal for the help.

Glad to hear all is well. It is surprising it ran "well" missing a turbo but I guess we have 2 for redundancy.
