I recently discovered the same thing while rewiring my dash. Apparently my flasher doesn't like low voltage. Once the voltage dropped to 11.5 ish, it slowed down then just stopped. Start the engine and she worked fine. I even had the battery tested and it passed the test. So, I just put my battery charger on it when I'm working on it for long periods without it running. Typical? I don't know, but that's the way mine is.
