Even though you have/read a good ground maybe as simple as one going high resistance, at bulb or elsewhere. Intermittent....fun.....not.

Maybe, but juice goes from fuse to flasher to switch. If it was a problem anywhere in a bulb circuit, other side should work. If I jump the flasher, that only leaves the input side of the switch. So, maybe just working the switch so many times rubbed off some corrosion...
