Yes, in fact I've been going through this for the last three months 
with my MacBookPro... for a long time I couldn't tell from the various 
blogs I was reading exactly what the problem was until I ran Apple 
Hardware Test, and it pointed me to the fact that it has to do with the 
fans not turning on when they're supposed to, and the processor 
overheats and shuts off. I've DL'ed and am running smcFanControl 
(http://homepage.mac.com/holtmann/eidac/), and I haven't had it 
shutdown ever since I had it installed.  My understanding is that it's 
a logic board defect, and when I get a chance I'm going to get it 
fixed, but for now controlling the fans seems to be working.
