You can try a new battery, when the power is low it shuts down by default. Try Z-battery.com or zbattery.com for unbelievably low prices on camera, phone and laptop batteries etc..

Two possibilities here. The lens housing is damage, and when you try to zoom it is unable to do so. You would be more inclined to get a message about this as opposed to the camera powering down.
Second option is a low power situation. If you are using non rechargeable batteries, you might find they are not up to the task. I have found this with few cameras. If you are using rechargeable batteries, they may be end of life, and no longer packing the same punch that the once were.
Although rechargeable batteries have 1.2 volts instead of 1.5, they can have more power with higher capacity. I tend to use 18mAh or higher batteries in my camera, especially for zooming, but make sure to use the guidelines for charging and recharging these so they will last a long time.

If it's really almost new, why don't you take advantage of the warranty?

Two ways to reset a camera: 1. go into the menu and find "reset"...follow the on-screen instructions. 2. Remove the card and battery...press all the buttons...leave it alone for 20 minutes...insert the card and then the battery...turn it on.

i would ask a specialist at a camera store to check this.

Usually means a weak battery or a lens alignment problem.

It usually means the battery is dead. If the battery is marginal, putting the camera in the review mode it will work.
