You can increase the memory available to pandoc, to say 2048 MB, with:

pandoc.exe +RTS -M2048

But the underlying problem is probably that Pandoc uses zip-archive to zip the EPUB file. It seems you currently need at least as much memory as the uncompressed EPUB you want to generate (but I'd verify this before filing a bug report there).

You probably also should scale down your images a bit since 2GB seems rather excessive for an e-book (even if it's a bit smaller when compressed).
