Oil pressure sensor going bad?

Today was the second flight, months apart with many flights between, that my pressure sensor was on the fritz. Pressure readings were all over and occasionally would get the red x and come back. The first time it was for about 5 seconds during takeoff, which I was able to abort and we looked into it and could not duplicate. This time, it was well after I was in cruise and lasted closer to 10-15 minutes.

The sensor is 503851-000 Oil Pressure Sender - Kavlico v2, 1/8-27 NPT, 150 PSI.

Any experience with this before I try to start troubleshooting?

I originally was thinking it was likely a connection with it going straight offline the first time before coming back, but with it fluctuating and going on/offline today, that doesn't seem to be likely to be an oil line or electrical connection issue that I can think of so I'm thinking it's a failing sensor. It's a relatively new install with very few issues so far - all except the D30, that thing is junk.
 
Far more likely a connection issue. Trace all three wires from the source (5V supply, ground and sensor). A bad connection in any of the three will yield the results you are seeing.
