Help with power issue

I am having issue with my power in zwift. I’m not sure if it’s an issue with my trainer, my connection, or something else. My power constantly goes to 0 and spikes really high. In zwift companion, when looking at my activity results my white power “line” is a thick area graph, not a line at all.
Has anyone seen something like this before? Thoughts on a cause?
