s60 Volvo - Bad Alternator or Battery??

I have a 2007 s60 T Volvo... I bought the car used and it has about 30K miles on it. Yesterday I drove to the store and went inside for about 10 minutes, when I came out and tried to start my car it was totally dead. No interior dashboard lights, no nothing... I had it jumped and it took the charge at first and then cut off again. Jumped it again and the charge stayed and I drove to another location parked, went in for another 10 minutes came out and it started fine. The car has been parked overnight and just went to start it and it is dead again. No interior dashboard lights but the headlights and the overhead interier lights will come on.
Do you think this is an alternator problem or a dead battery?

Thank you

Let me add that is was running perfectly fine up until yesterday..

If the headlights come on at normal brightness then the instrument cluster should come on. I think this is a more serious problem requiring the car be scanned for codes to see what those may point to.
When the car jumping you was attached to yours via jumper cables did that make the instrument cluster warning lights all illuminate as normal when the key was switched on?
