Which gives it enough juice to start but soon as I unhook the Jumper, it dies again.
I leave it on and the car runs for a short bit then dies.
Does this mean the battery is shot?

Maybe the battery, alternator, regulator, bad ground. Get it started, drive it to a chain auto parts store, and ask them to test it for you. If it is bad and you purchase a battery from them, they will install it for free.
This is in the US, not sure it applies elsewhere.
