Unexpected shutdowns with no warning - event logs attached

This has been happening since last 24 hours, My toshiba laptops shuts down automatically without showing any warning, the first it happened about 20 minutes after I turned it on , after the shutdown I again hit the power button and it started normally but after 2 minutes it happened again. I put it away and this afternoon I again turned it on and the same happened after 15-20 minutes this time when I tried turning it own it was not responding, I placed My hand underneath and it was hot around the fan and exactly under the touchpad. After 2-3 minutes I was able to turn it on again but it shutdown after a minute.
The fan is working , I do not see any hardware problem as well because its working FINE right now (been on for about 40 minutes)
I just checked the event logs and this is what I for the unexpected shutdowns.
