That pretty much puts narrows it down.
Probes and the wires can show intermitent failures.
Your going to have to start troubleshooting them.
My technique on the wiring like this is...
Disconnect the probe wires in the cockpit where they terminate.
Take pin, like a sewing pin, thin, poke one in each end of one wire. One at the sensor end, the other at the other end in the cockpit. Your just trying to get the pin to make contact in the wire.
Hook an ohm meter to the pins using alligator clips or something that will keep them there, preferrably a meter that has sound, and start jiggling and moving things around.
Do that for each wire all along the route.
Once you do that, if nothing is found, you can swap probes around and see if the problem moves, trying to determine if its the probe. You dont want to throw money at a probe till your convinced thats the culprit.
