Really need a gauge in the oil system or a scan to see the IPR/ICP.
With the way it went on you my WAG is electrical or the IPR has the drain open. (stuck or bad o-ring)

No ... a bad injector O ring can cause both of the problems you have ,, no start & empty res.....

You can also pull the valve covers & watch for oil bubbling up from the base of an injector ( or two)....A guage will isolate which side to look at....

I did not see if you checked the IDM relay.
You know the PCM is up (WTS lamp), so exchange the relay with the IDM to see if you loose the PCM.

You can dead head the pump left side/right side.
One at a time. This will find a leak in one or the other head. (inj o-ring)
Also can pull the VC's and look around the inj's.

My WAG is still the IPR. It happened to suddon.
Could have blown an inj o-ring if you were out playing with the truck with the chip turned up.
