Try changing the pram battery.

I have the same iMac & had exactly the same problem. For me, it turned out to be a faulty Ram chip in the upper slot (was 128). I took it out leaving the 32Mb in the lower and it worked fine with its then OS - 9 (once I turned virtual memory on). I bought a new 128Mb chip and its worked ever since. Then again, my beige G3 also did the same thing and its problem was the pram battery as seanc suggested.
