Oil pump cutting out???
Have a 95 5.2 new to me drove roughly 200 miles after sitting for 5yrs did basic tune up, oil change, fluids, before driving. Was idling after about 5 min of driving, started knocking loudly, lost oil pressure. I shut off checked oil..was full...restart still knocking loudly, shifted gears moved jeep about 20ft shut off, called for a ride, 15 min later when ride showed up I tried one more time. 2 seconds after start initially knocked. As I went to turn off oil pressure shot up knocking stopped. I drove home. About 3miles. Normal as can be... any input appreciated...
