There should be options within your IRA to move the money out of stocks or mutual funds and into a money market account or other investments. Would I move it out of the tax sheltered IRA? No, I would not, that's just going to cost you a lot in tax money. However, moving it around within the tax sheltered IRA is a different story. You could cash out the stocks/mutual funds and move it into a money market fund without having to pay taxes on it.
If you move it to cash (money market fund) you'll lose money to inflation but you won't be exposed to further downturns of the stock market. I wish I could tell you what to put it in that would be protected from market losses and inflation but your guess is as good as mine. Investing in marijuana is about the only thing I can think of, we sure don't seem to be running out of potheads.
