To be clearer, it isn't Ollama-specific. I first encountered the issue with Stable Diffusion, and it's remained since, but the GPU that causes it isn't currently inside any machine; I replaced it with a 3090 a few days ago.

I'd recommend trying stuff that exhausts the VRAM. That seems to be where thinks get flakey for me (RX 7600 - 8GB), especially if running a desktop too.
