If your page takes substantially longer to load than conventional industry norms, especially if it takes so long to load that it times out, search engines may consider it a poor user experience and choose not to index it. In that instance, they may just be unable to view the content.
You need to check first if you optimize your online store properly, does it have all information, are products added as they should be, do you have enough keywords on the page, how is the UX on a specific product page, did you add title tags and meta-tags, and so on. If you missed doing something from this list, it may happen that Google refuses to index the store because it's not optimized well.
