Trying to find a awk only solution, the script has become uglier and uglier, but here it is:
Code:
$ awk  'NR==FNR {T=(T?T:"\n")$0; next}        # save trailer from tail process substitution below
        FNR<3   {H=H$0(H?"":"\n"); next}      # save header in first two lines
        /^$/    {exit}                        # find start of trailer (= empty line as specified) and quit
        !((FNR-2)%N-1) {if (fn) print T > fn; # every N records:
                        fn="file"++i;         # create new filename
                        print H > fn}
        {print > fn}                          # print to just created filename
        END {print T > fn}                    # add trailer to last file
       ' N=1000 <(tail -2 file) file          # process substitution, not in all shells available
