Got my Pi about ten days ago. At first thought it was something I was doing wrong but now I'm not so sure. The Pi is not in a case but sitting out in open air. The power supply, which i tried two and two cables, is according to specs on the adafruit website. I have been doing my homework and trying to find a reason for the auto shutdown and have come up with nothing but inadequate power supply, improperly seated card, or corrupt OS. I have checked all of these.
I have Occidentalis installed on a 8GB micro Sandisk card that is on the supported card wiki. The mico card is in a low profile adapter from Adafruit. The batch number on the back of the board is FNXM121171526.
Not sure what else to try, look at or how else to troubleshoot this problem. My plan is to host a website on this card and I need to have confidence that it will stay running
