I had a sensor issue with mine. Symptoms were similar and it would go away
at higher rpm and/or shutting it off. I ended up replacing the sensor and
all troubles went away. Also check the wires - if they are corroded etc
they can cause issues.

I also added an oil pressure gauge so now I keep an eye on that.
