OK, I downloaded your file, and noticed that it is 1GB… After taking a closer look, I think you can benefit from some optimizing techniques to reduce the size of the file and that may in the end minimize the number of crashes you are experiencing.
Here is a link to some tips to consider.
Just running the material resizer on the sketchup model can make a huge difference.
Also, be very selective to use efficiently modeled component assets that just enough detail for your needs. I suspect the components you are using are very large in terms of MB.
After optimizing, try exporting again. Let me know if you are still having trouble after that.
