Hi Kevin. I had a similar need a couple years ago and someone on the  
ImageJ list helped me put together a small macro that does what you  
described you wanted it to do:

a=0;
n=getNumber("Frame reduction ratio (1/n)", 5);
for (i=1;i<=nSlices;)
{
        run("Set Slice...", "slice="+i);
        if(a!=0)
                run("Delete Slice");
        else
                i++;
        a++;
        if(a==n)
                a=0;
}
