Sigma Lens

I have one 24 - 70 Sigma lens which I use on my K100 and when I get into the menu's like to format my card I get kicked out in a matter of seconds, No matter what setting I am changing. This happens with my K-20 as well. Could this be some kind of electrical connection in the lens? The lens produces nice pics.

This only happens when that particular lens is mounted?

If it is just that lens then I would say there is certainly something wrong with the internals and needs to be repaired.
