I started having this problem just last week. I couldn't get my lude into any gear, even reverse. So I said screw it. I came back like in 30mins. restarted my car and then I was able to shift into any gear with ease as if it never had any problems. Then the next day it did it again, and again I waited and no problems. I haven't had this problem in about 5 days now. Is this an indication that my clutch is going out?
