Heap out of memory on all but dev builds

Any time I try to use electron-webpack for building or production testing I get a heap out of memory crash. It works fine if I do `electron-webpack dev` but that is the only case it works.

I am currently trying to make a win distribution with electron-builder. Do I need to make my own webpack files. I thought that electron-webpack would handle this for me, since electron-builder is recommended.
Here is the heap error.
