My MBP shuts down without warning after about 15-45 min. When I boot it up again, however, it remembers the programs I had on and it reopens them. I have tried to reset nvram and smc. I also took it to the apple store and they couldn’t find what was wrong with it. They suspected one of my applications was causing a kernel panic so I uninstalled it but it still is shutting down just as frequently. The battery still keeps its charge and it shuts down whether it is plugged into the power or not. I have noticed however that it shuts down more frequently while watching videos, most frequently with hulu though. A friend of mine said to try to make a new profile to see if it shuts down randomly on that profile. I tried it and it shut down less frequently (about 30 min to 2 hours). It still doesn’t solve it though and I’m not sure what to do. Thanks for your help!

I think you need to monitor the systems temp. Download this app: Temperture Gauge Pro. You’ll need to buy the full version as you’ll need the logging function to watch what happens just at the point the system blinks. Post a screenshot of the TG Pro and systems log file so we can see them.

Have you replaced any hardware right before this started? If not, my guess is Motherboard may be on its way out, excess dust in unit causing overheating or another part is going bad and causing a glitch with Motherboard.
