oil pressure gauge

so I have come to notice that after I drive my truck for over an hour straight like on a freeway without stopping I'll come to a stop and when my rpms go below 1000 my oil pressure gauge will drop a little bit and start flickering like crazy. It goes back to normal once I hit the gas. Any suggestions of what could cause this?

The sensor (which is a pressure switch , these are dummy gauges) is going bad .

My mechanic checked mine out while he was under the hood. Said it was the switch. The pressure and oil pump were fine. I think there is a TSB on this.
