I suspect your Mac is overheating to the point that it shuts itself down. I would install a temp/fan monitor like iStatPro http://istat-pro.en.softonic.com/mac Take a look at what your temps and fan speeds are.

Yes it does sound like overheating except sometimes it will boot up and stay
on all day. Now it will not boot up at all.
The power adapter lights up
The battery lights are good

One added note:
The light next to the camera should flicker (in a dark room) when there is power
and the power button is pressed. Yes the light does flicker.

I've owned a MacBook since 2007 and have never seen the camera light flicker, but that doesn't meant doesn't. You can try resetting the SMC
Shut down the computer.
Disconnect the MagSafe power adapter from the computer, if it's connected.
Remove the battery.
Press and hold the power button for 5 seconds.
Release the power button.
Reconnect the battery and MagSafe power adapter.
Press the power button to turn on the computer.
It's sounding more and more to me thatyou're got a hardware failure, but I wouldn't want to just guess what it is. The computer may need to be taken in to determine exactly what it is.

OK I removed the battery and power cord and held the power button
down for 5 seconds and it started and so far is staying on.
I'll just leave it on.

Remember that we suspected overheating. Download IStatPro or some other application that will allow you to monitor your temps and fan speeds.
