MacBook randomly shuts off and won't charge

Question

I have a 13 inch MacBook that's less than a year old. For the past several weeks I've been having a problem with the computer randomly shutting down. It usually does this even though it's running on A/C power.
When it happens, the computer shuts off and the charger no longer works (ie no light). The computer will turn right back on if I push the button, but I have to unplug and re-plug the charger several times before I can get the light to come back on. Also, after the computer is turned back on, my date/time settings are always wrong, and my computer doesn't automatically remember my wireless network. Any help would be great.
