Jacuzzi J-315 Lights @ Headrest & Waterfall Lights Not Working

[DonandKiki]

We have a 2009 Jacuzzi J-315 and use it year round in Virginia. We don't use the lights very often, however , the other day after having the lights on for about 5 minutes the lights began to randomly flicker. After about 15 seconds, the upper lights (head rest and waterfall) stopped working. The lower light remained illuminated. I also smelled a slight electrical burn smell. The lower light had no issues......

After our twenty minute cycle I turned off the circuit breakers. After a day or so I powered back up, turned on the lights and everything seemed to work fine....... any ideas on the electrical smell??
