2015 jeep pentastar 3.6 oil issue

[OVERKILL]

Monitored the pump solenoid. When temp is reached, solenoid locks in and remains in alternate pressure mode.

Yeah, so that definitely doesn't explain your momentary complete loss of oil pressure. Normally that would be it sucking air or the pick-up briefly getting blocked.

Not to state the obvious but if the oil pressure was checked with a mechanical gauge the sending unit may be going out. Start with the easiest and simple things first.

I would "start" by finding a new mechanic.

No codes? Usually they will code if pressure drops. OEM cooler?See many issues with aftermarket. Inspect oil filter cap, have seen the center part of relief fall out and cause issues. Also see the oil galley plugs in front of head , below cam gears get loose/fall out on a few
