Welp, went for a test drive again after a solid warm up period...15 mins, just to double check. Cut out less than 3 miles into the drive. Got 2 cranks out of these two freshly charged batteries (Motorcraft batteries 11/21 manufacture date) and it got low where it wouldn't turn over no more. For s**s n giggles, pulled both batteries and had them load tested at an AutoZone down the street and they both failed. Popped no codes when it shut off this time and fuel pressure was 60 psi when it happened. Taking the batteries in under warranty tomorrow. I am concerned that the PO put an unnamed reman alternator in it. I dont *want to drop the money for a new alternator, but will if I need to. Gonna pull it tomorrow and have it tested just for a little assurance that it's ok.
