Hello. I need help finding the issue with my edge. I am losing power when I accelerate.And when I get to my destination and I turn my car off , it dies. I have had a new battery, along with 2 new alternators, put on It.And we can't seem to find the issue. We have checked the ground wires. We check the serpentine belt, and I'm trying to find someone who may have had this issue before.Who can help me navigate and see what the issue is
