This is a common occurrence I believe.

There's something called the goal disclosure effect where telling someone about your goals can reduce your motivation to achieve them.

There's also a 'dopamine reward prediction', where your brain releases dopamine for signals that you're on the path to success, which includes talking about, planning, or imagining success.

As a result I've also learned to not talk too much about anything I want to build before I actually have built something.

I feel like this article might be slightly different though in that you're moreso just thinking out loud, more like rubber ducky debugging than talking about some idealistic vision you're striving for.

I often feel that the interesting part of a project is working out how to do it in sufficient detail to be sure I can do it. But from then on it's just work and I lose interest even if the only person I have explained it to is myself.
