FWIW, I wouldn't start the pitch with the fact that the script is 25 years old. Hollywood wants fresh and new, and whether it's done the rounds or not, it gives that impression.
Listening to the youtube pitch, you aren't selling me the sizzle. You need to sell the emotion, the feelings, the ride, the drama, the trouble, the connection.
Also, in the pitch, you have lines like "You'll laugh when..." "You'll cry when..." which is telling, not showing. And suggests that the script could be the same. It might very well NOT be, it might the greatest script ever, but this pitch is not gonna get me to even read.
And to be honest, rather than a very slow Power Point-esque presentation, I think you would be better served nailing you pitch to under three minutes and having the camera JUST point at you and YOU sell it. Everything that made you passionate enough to write the script and stick with pushing it for 25 years, should come through. Doesn't need to be all hyper and jumping and shouting, just let that passion come through.
In truth, beyond hanging around to offer some kinda feedback, as a producer, I wouldn't have watched much beyond the first 30 seconds.
Additionally, because it's an emotional story, have you considered reworking the project to have at least one of the two main characters be female and look at pitching this to Lifetime.
While not exactly a ton of fun, I hope this helps.
