Had a similar problem on my 83.5. I checked everything & intermittent problem continued - but no actual overheating. Finally the primary coolant top popped off - spewing coolant all over. I refilled & noticed that primary pressure cap didn't seem to be level when tightened. I loosened & retightened - level & all well. My only conclusion is that cap gradually loosens from heating/cooling cycle. I had
replaced the cap with an after market - don't know if this was a contributing factor.

Pulled into the adjacent parking lot and checked the coolant levels.  All were OK.  Upon restart, the light did the usual 3 second flash to indicate it was working, turned off and never came on again during the 6 hour drive (over 2 10,000 foot passes etc.)

The only anomaly, on the 45 min drive is after sitting for an hour, the temp seemed to climb to normal operating temp faster than usual.
