Previous Shutdown Cause: -128

Everyday my mac instantly shuts down once or twice a day, no warning signals, just instant blank screen. I have performed the standard and extended hardware tests, which reported no found problems, and I have reset the PRAM with cmd + opt + p + r. However, the problem remains.

What could be the cause of this and how to solve it?

Kernel.log reports Shutdown Cause -128. Complete log for a shutdown scenario:

At the time of these shutdowns does your iMac feel hot, particularly near the top vents?

Are the intake (bottom) and exhaust vents (top) clear?

Add a temperature monitoring utility like iStat Menus, iStat Pro, Temperature Monitor, Hardware Monitor, etc.

I have installed iStat Menus, waited for another unexpected shutdown, and noticed no significant increase in temperature. So we can exclude overheating.
