Atwood water heater won't stay on.
Just bought a barely used 2017 Shasta Oasis camper, hope I didn't buy somebody else's problems. Anyway, the Atwood water heater will not keep running after it kicks on, it stays on for only about a mi...

I have a problem very much like what Paul1944 describes...
-- New Atwood Gas G6C-8E-SP water heater in my RV
-- When Remote Switch is switched on, light turns red, then off within 10 seconds usually
-- Water heater stays on for 10 to 30 minutes, then turns off
-- The Remote Switch light does NOT turn back on
-- I cannot turn light off and then back on for an hour or two
-- After the shutdown, the sink running water is definitely warmer for 10-15 seconds so I know the heater has heated water. I assume that means there is water in the tank.
-- I installed a new RV Water Heater Thermal Cut Off Switch Kit Replace for Atwood 93866 - understood that it probably wouldn't make a difference but installed it anyway. It doesn't appear to break after cutoff and water heater can restart sometime later (like an hour or two later)
-- I purchased a new Atwood 91447 Thermostat Assembly and can install it if that would make for a difference

Flame is more orange than blue.
There is a wire with what looks like a resistor in it, what is that for?"
8E has separate controls for electric & gas
ELECTRIC:
120VAC comes from a Circuit Breaker to on/off switch (backside of WH Tank) then thru set of T-stats to element (also backside of WH Tank)
GAS:
12VDC comes from Fused source to 'thermal cut out' (fuse in clear tubing----it blows at 190*F if flame blowback occurs and stops ALL DC to water heater. One shot device --replace if bad)
From thermal fuse DC goes to/thru TT-stat then to circuit board
Circuit Board then sends DC to ECO/Gas Valve AND spark electrode
From Old-Biscuit earlier comments, I take it that I should pay anything to the follow... Anything else?

When flame lights off......is flame BLUE and quiet (very slight roar)?
IF NO (YOU stated more ORANGE then Blue)
Might need to adjust air shutter ---typically only needs to be roughly 1/4 open
Might need to clean orifice (soak in alcohol/air dry), clean burner tube (small bottle brush)
