jeep commander electrical issue

My Jeep commander 3.7L had recently suddenly died while driving with the
lights dimming, dash lights all went off and flickered before engine stalled to a
stop. Tried to crank a couple times after before it lost all power to the entire
vehicle. Got it running again and it has since had the pattern of running for a
few days or a week not exact, then the battery symbol will suddenly show and
shortly after the ABS, traction control & 4WD lights show before dying again. It
started right up when jumped but now when jumping iit won’t even crank, just
clicks once and that’s it. Battery and alternator both replaced so what kind of
screwed up issue is this ?
