2004 6.0 delayed start

Hey guys so I’m new here and new to 6.0 life. Ok so long story short. I definitely would appreciate your help. I have delay start when it’s sat more than say 5 minutes or so. I hit a bump (pothole) and it caused a vacuum line to come off for ac, no problem, stopped at orileys thinking ac ran dry so as I’m filling it I look at my gauges and it’s on no oil pressure. Truck runs great, has good pressure when I hit the throttle just a touch above 700 rpm. I’ve seen threads for lvop and hpop symptoms. Now they all cover what I’m going through but rule of thumb to them is it wouldn’t fill the bowl. My oil filter housing gets full when I crank it from the jump wire. I replaced filter with oem and cap. New oil, even after priming the oil housing it’ll delay start, cold has oil pressure, 1-2 minutes of running it drops at the gauge, says check gauges but continues to run and sounds no different and still runs fantastic. I’ve taken the bottom plug out for the lvop and it’s f
clean no debris inside, haven’t gone as far as taking out my ipr or icp. Mostly because my bowl fills on command. Am I thinking wrong or should I be looking elsewhere? Thanks for any input. I even checked for a bad cluster but seems to work fine.
