I have replaced both the 120v and the propane thermostat on my Suburban twice each over the past 5+ years full time.

If there is a crimped on connector on the end of the wire there may be a bad crimp, maybe crimped on the insulation too much and barely making contact with the wire. Also possible the wire has a break inside the insulation some where

An electrical contact cleaner may help. Just had a problem with my ZTR not starting. Pulled some connectors, sprayed with elec cleaner, solved the problem.

Some of the issues with Suburban t-stats
1) Crimps on connectors
2) Wires getting chaffed due to rubbing against edge where metal is folded over
3) Connecting wire between t-stats
4) Loose/dirty contact between t-stat and tank wall
