A search brought up similar questions but my situation involves a ceiling fan w/ lights that operates via a battery powered remote.
This fan is on a circuit that previously had a total of three switches (master bedroom). One of the switches was taken out of the equation during the fan install (numerous years ago), but over the past 12 mos. or so, the lights go off by themselves. I have always used 4 CFL bulbs, which are fairly low wattage, originally without problem.
Sometimes the lights go out after being on for less than five minutes, other times they stay on for 30 minutes or more before being "extinguished". I have never noticed if the fan operation is affected the same way. What gets the lights back on is switching the two regular light switches in some order/sequence, which I haven't figured out, but the lights tend to eventually go out again w/o using the remote.
As far as I can remember, the original lighting didn't have any problems, and the fan/light fixture has worked okay for the first few years.

It’s hard to tell for sure but if it was working normally until recently I’d say the electronics for the remote control receiver are failing.
You can bypass the remote unit and connect one of the wall switches directly to the light kit. You can keep using it that way or replace the remote and receiver with a universal ceiling fan remote control kit.
