constant crash in 3d sketch

I am not having a good morning. 3x I have crashed (thrown out) of SW while working in 3D sketch (part within an assy).  It is when I am near the end and I lose all the work.  B/c it is within a sketch autorecover does ng.  Does anyone else have this problem?  I now feel like I have to do it in tiny bits and pieces, save, go back in, do another piece, get out, save, etc.

I am using 2011 SP0, all my hd'we is fine and cert. SW (see profile for particulars if interested).  I'll upgrade to current SP but regardless, this really should not be happeneing.  I have many more of these wire harnesses to do and if I have to go thru this each time it will take me forever
