Brian, This grid size (151,987) is well within the 750,000 defined size. The data in the file posted below is grib1, with 330 fields for 2005072112F003. I was able to decode it both with dcgrib2 as well as nagrib. Have you tried nagrib? I don't know what trouble you are having, so can't give you any other advice at this time.
