Besides high fuel pressure, which you checked, the guy in the book says it could be a saturated evaporative canister, a defective canister purge valve, a defective PCV valve, or contaminated engine oil.

ok, that's a clue that sounds familiar.
years ago I would get issues with the evap stuff on a Taurus. tank hissed,
turns out there is a restrictor orifice in the line that got plugged up. it looked like a short tube or splice.
this one was near the evap solenoid, no idea where it may be on a Ranger.
not a for-certain, but something to look into.
