Three things I would try:

- try setting the filename of the target image, as opposed to using "put

- save the stack each time after exporting 10 to 20 images or so

- if saving every so often doesn't do anything, try deleting the image
object, and creating a brand new one, and saving, as opposed to putting
empty into the existing image

Hope one of these helps.
