If this started happening without your having made any changes and without a warning of low disk space, then it's likely that the boot drive is failing, or that there's some other hardware fault. Back up all data immediately, then run the Apple Hardware Test.

Even if the test is negative, you should make a "Genius" appointment at an Apple Store to have the machine tested more thoroughly.
