I recently (about 1 month ago) bought a MacBook Pro (13 inch) and when I'm using it it often goes in to sleep mode, while I'm still using it and while I still have battery power (it also happens when connected to a power source).
I downloaded iStat to monitor the fan speed and temperature and I found the temperature of "CPU A" to be between 60 and 72 degrees celsius. It has been 72 degrees for a while now. The other parts are around 30 degrees celcius except for Heatsink A, B and Northbridge 1. Heatsink A is 0 degrees celcius, Heatsink B is 58 degrees celsius and the northbridge 47 degrees celsius.
The fans run at about 2600rpm to 2800rpm (sometimes as fast as 3000-4500 as well, without going into sleep mode) but rise to 5500-6000 before going into sleep mode. First the lamp that indicates your Mac's sleep mode tries to do the on and off cycle but doesn't complete it. First it's bright, then a little bit less and then bright again. Eventually the fans stop zooming and the normal sleep mode rhythm is shown by the indicator. By closing the MacBook and opening it up again the MacBook wake's up. That is, until it decides to suddenly go in sleep mode while working again.
This is my console log of a few days ago when the problem occured:
