oil pressure guage on 2004 Ford F-250 Super Duty

I started the truck went down the block to stop sign. When I stopped noticed that the check guage light was on and oil pressure guage needle at the bottom of guage. I accelerated from stop sighn and light went off. Stopped Again and light came on and guage at bottom again. Checked oil level and is fine.
