Sounds like there may be a shorting wire, perhaps in the morning after rain or dew, as soon as the engine warms up, it dries it and eliminates the short until the next time. Look for a wire with a broken outer casing. When the flasher is going bad, it will flash only when the voltage is higher. Perhaps after warm up when the battery is fully recharged the voltage is high enough to make it flash. Get a new flasher, they are cheap but they are a pain to replace.
