3 reasons I can think of that are most common.

1. The power brink might be failing, you would need to try with a new one.
2. The battery might be failing, try with it out.
3. The CPU/GPU might be overheating for that you would want a program to monitor the heat, HWMonitor is a good option. http://www.cpuid.com/softwares/hwmonitor.html
