When you get back, you should get to the bottom of this, to have any reliability. Doesn't sound like a hole in the tire, so must be at the tire beads, or rim tape, or valve. Submerged wheel and tire section in water in basin should show a valve leak, or bead leak. Rim tape, I guess would show a leak through the spoke holes, but with a double-wall rim, that leak could go to ALL spoke holes, so you don't know exactly where, only that it's the rim tape and you need better stuff.
One of the reasons I just bought a pair of Rovals for my new Time Machine is I wanted to try another brand with tubeless. Because of the puncture risks where I live, I am a tubeless convert. It absolutely makes sense (and cents) out here. But the only wheels I have had so far that are tubeless capable are Reynolds. I have all but given up on getting the rear wheel of my AR80 set to seal and now I'm having difficulty with the front wheel on this AR41 set.
I find that once they seal, they are good for months. I'm OK with doing routine maintenance 2-3 times a year but I really don't like the rim tape thing. Tubeless wheels come from the factory with some kind of heat formed sealing tape that seems to work really well. I don't know why anyone would remove it, but it happens. I just wish there was a way to apply that by the end user.
