Why does my Canon SX260HS shut down while I am shooting?

I can take like 2 shots then it shuts down. Lens closes. I press restart and then the same thing happens. I miss a lot of shots while restarting. Anything I can do?

This is the message:"A camera error has occurred. Will shut down. Restart camera. E32"
