Had that coolant loss problem for the first 2 years. It quit loosing coolant but I'd still get a low coolant warning anytime it was really hot, even though it was full. Had to take the top cover off in places like Phoenix and Las Vegas so it wouldn't shut down.

 

Check your oil on dipstick & sniff to see if you can smell any coolant.

Probably warped head/blew head gasket & it's leaking into your oil.

Both are not out of the ordinary.
The older ones especially are very sensitive to case pressure & too much oil or too thick oil in cold environment can chew that HG apart.

 

If it's not hitting the ground check for any white marks on engine
You could have a seal leaking under pressure and evaporating at leak point due to heat from engine

 

So you see any white or red marks around the overflow cap? Look on the underside of your cover when you remove it, do you see anything there? Many times that material will absorb the coolant.

 

When I mention old, I am referring to all pre-Kohler engine models as a rule.
If yours is the orange or yellow engine then it's pre Kohler.

Did you replace the over fill cap with another one that has a breather hole in the top?

Was boiling out of our old RM when hot out, then dripping onto the belts below causing banshee squealing & premature belt breakage.

See if you can ziptie the cover sensor button shut & run it on a hot day on very black asphalt with cover off to get a better view.
