2005 chevy silverado Low oil pressure warning.

I get 10psi oil pressure at start up. Oil psi increases under power to 20 psi. After driving for a little bit i come to a stop and i get a low oil pressure warning. Ive had the oil pressure sending unit replaced. Used a mechanical gauge on the filter at idle 20 - 25 psi under power it goes up to 40-50 psi. So with these kinds of pressures the oil pump is good. The gauges were replaced and still with new gauges it reads low on idle and under power. Any ideas???????
