'97 Stumbled, stalled, then no start

This is a '97 E-Superduty

The details:
1 week ago during a two hour drive:
-Pulling a loaded trailer, had one light miss going up hill while cruising. Felt like the torque converter unlocked then locked quickly.
-Two successive hard misses while accelerating up an on-ramp 45 minutes later
-Two successive lighter misses while cruising (~3500 RPM) 10 minutes later
-Drove fine otherwise. No loss of power, no weird smoke

This morning (hadn't driven it in a week):
-Started up easy no problem
-Placed into gear idled a few feet, then stalled. Restarted easily
-Putted around the parking lot, had one more stall and a couple stumbles.
-Stopped truck and restarted 10 minutes later, no problem.
-Putted around the parking lot, parked it, stalled, and hasn't restarted since.
-Cranks without issue, no sputters, no smoke, just cranks and never starts

What I've checked:
-I checked the oil and it was low, just enough to register only about 1/4" in the dipstick, oil has been filled to proper level.
-The only mod is an E-fuel Conversion (~2500 miles on it), 65 PSI confirmed at the rails
-Unplugged ICP Sensor - No Change
-Idle controller registers 105-110 RPM while cranking
-WTS light turns on, then off as it should
-No check engine lights during any of this (it does work)
-Gauges always registered normal
-No codes active, or stored

Is this simply a case of needing to pump of the high pressure oil lines? Did they run dry, maybe?

Can the CPS send a bad signal, even though it registers properly on the idle controller?

Thanks guys!

HPOP reservoir is full.
CPS was changed out for a new one.

No luck, not even a sputter.

Just in case anyone comes across this thread with similar symptoms, it turned out to be the IDM. I borrowed one from another truck and it started fine. Now to find a replacement for a reasonable price.
