My friends Grand Cherokee did almost the same thing. His wife let it sit 5 or so minutes
It actually did overheat, but soon was normal after she cranked it back up
They sorta just kept this "Procedure" up, over time, as it became more and more regular
He and I kept checking things. Fan operation, replaced thermostat, etc
Finally, the "procedure" failed to work!
We found the FAN RELAY, would ACTIVATE, But the contacts necessary to complete the FAN MOTOR CIRCUIT, were Kinda Burned.
Even though they were contacting, they were not Transferring Juice from one to the other.
We found this out by careful, RELAY dis-assembly and testing!
All along this was the problem, getting worse and worse.
Sitting for a few minutes (cooling maybe?) Allowed it to come alive again
We wanted to be positive, that this was the problem, before we stuck another in, and waited to be called to another breakdown!
