Have a Yukon, when I was driving battery light came on along with message "service battery charging

Have a Yukon, when I was driving battery light came on along with message "service battery charging system" then all lights/sensors come on such as ABS, airbag, tire pressure, Stabilitrak off, traction off, check engine light, etc.  Once all the lights come on, then the lights begin to dim followed by the truck dying.  I then have to charge for about 30 minutes and can drive about 15 miles before it does it again.   What could possibly be wrong with truck?  I've been told alternator, to needing an new electrical system, to a new battery.
