Car will not start, absolutely no power, lost power while driving

Hello,

It sounds like the issue could be that the alternator is not providing adequate charge to keep the engine running.
Typically, with a bad alternator the engine can stall, usually when coming to a stop and you won't be able to start it back up. And jump starting will start the engine but will shut down when the jumper cables are disconnected.

I have attached diagrams below for your reference.

Let me know of any questions.
Thank you.

The battery is good, it will not start, and no power if you try and jumper box or car to car. The only time I get power and everything is work is when I jump from battery to the cable post in the under-hood fuse box.

The engine is a supercharge 4.2.

You might want to get the alternator tested. It does sound like a faulty alternator. If the alternator tests out good, then you are looking at wiring issues.
