Resolve 15 Crashes on Render

I created an 8-second video using a 1920x1080 PNG image and a burn-away effect created in Fusion, followed this online tutorial for that as I'm new... youtube /watch?v=4XDlKUpYUCo (I can't post urls...) It plays, though-be-it choppy, within the fusion tab while creating it. I did get a GPU memory full from time to time. Side question: How does an 8-second clip of a PNG and burn effect fill up 4GB or GPU RAM? Resolve crashes on render around the 37-43% mark every time. I never get an error message, it crashes hard and exits out to the desktop instantly.
I've tried multiple output codecs, changing the render speed down to 1, reduced the video to 720p from 1080p; they all crash Resolve when I try to render.
6800K CPU, GTX 970 GPU with 4GB RAM, 16GB system RAM, Win 10 Pro
Any help would be greatly appreciated!!! Thanks
