I say your battery is low. You can try a trickle charger to see if that resolves this, but if it doesn't its time for a new battery.
My car used to shut the radio off after a few mins. 1st time I took it to the dealer, they charged the battery and said I'm okay. It happened again 2 weeks later and I told them I was using a trickle charger, so they finally replaced the battery. I also drive a lot, so my driving profile didn't concern them.
