Default What electrical problems would cause a vehicle to die?

First off, sorry if this is in the wrong forum, I was unable to find the Saturn mechanical and maintenance forum.

Here'* the deal. My Saturn jumps fine but dies after running for about 2-10 minutes. After it dies, I check the battery with my voltmeter which reads about 10-11V. The battery is obviously dying so I removed my alternator, had it tested (tested good) and purchased a new alternator just to be sure. Same thing happens after new alternator is installed. I have checked all fuses, grounds, and I have checked for free spin on all the pulleys.

I am stuck and have no idea what else to check. I would appreciate any help or direction you can give me. By the way the battery is brand new and the starter has also been replaced. Positive connections and ground connections going to and from starter, alternator all look fine.

you try cleaning the cable ends, you cant really see if they are good or bad. you test the voltage at the battery with it running?

Battery terminals and cables look great, voltage while it runs is about 12 and slowly drops until it dies.

the diagrams i have dont have charging schematics for charging. there could be a fusible link blown if it has one or the enable circuit is bad. and like i said you cant look at a cable and determine weather the connection is good or bad you have to clean it with a file or wire brush and the point that it touches on the body or engine until both are shiny
