Also, my Takeuchis all have had cold solder joints on several of the relays.
In this panel, the relays, WITHOUT a Phillip's screw in the bottom, can be popped apart, and the cold joints repaired. The ones in question are actually three relays in one, and have multiple connections in the same housing. Pretty sure it's K & L. The ones with a screw thru the bottom have never been an issue.
Even replacement relays have the same malady, so, I stopped buying them. Just resolder the cracked joints within them, and it'll never happen again.
Intermittent shutdown or pilot disable are the most common symptoms.
