Random question: Does she start acting up as the light starts to fade, but she's fine until it starts getting darker?
If she's fine until it starts getting dark, I'd get her eyes checked by a vet.
My mare was like that all summer. She'd be totally fine (pretty much, she's rather, controllably, hot as it is, so her fine isn't "dead" fine, it's perky, alert "fine") until it started to be dusk-ish. When the light would start to fade, she'd start getting really scary. She'd spook at practically anything when she was basically a spook-proof during the day.
So I started wondering about her eyes, and when I had the vet come out when she scratched her eye this last fall, the vet told me that she has some changes to the very back area of her eye that make it hard for her to see at dawn and dusk. There's nothing anyone could do about it, it's just something about her.
So basically, she really couldn't see and that's why she started getting so crazy as it got dark.
Now, I just don't work her at dawn and dusk and she's fine!
Hopefully, that's not what it is in your case, but in case it might be... :)
