Troubleshooting intermittent faults from thousands of miles away is a slow process...
Was it raining the last time the thing worked ?
Have you checked the ground at the heater and the frame ?
Take it apart and look for corrosion ,
you want shiny metal to shiny metal
visually clean and physically tight.
Same deal at the battery terminals too.
How far from the battery to the W heater ?
How old is the battery and what is the voltage after an 8 hour period of nothing on , including charging ?
Do you have a volt meter ? 2 digits to the right of the decimal point would be a plus. Measure right on the battery posts.
If you don't have one , buy one. It will save you way more than it costs . Mobile RV mechanics aren't cheap !
The thing works .
Most likely your spook is starting to sound like electrical and could be found where the water heater is grounded........
I said could cuz it could be the positive side too.
Running a dedicated pair of wires directly from the battery (with a fuse) can make a cheap test rig as well as a final solution .
RVs are rolling earthquakes , all electrical connections should be checked for looseness and corrosion regularly . Once a year even if you don't go anywhere . Every trip if you keep having gremlins till you find it.
It can be a PIA but you don't have to mow your lawn !
