Hi @Erin5FEF:
In my experience, either the whole file is placed or InDesign crashes. Like @Mike Witherell and @James Gifford—NitroPress, I suspect the content is there but isn't visible, most likely due to Keep Options or maybe a series of images or long tables.
Here's one more idea: select a few of the last words you can see in InDesign, and then choose Edit > Edit in Story Editor. Is the remianing text visible, but under the overset line? That means it was imported but doesn't appear in the Layout view.
If you see text under the overset line in Story Editor view, click your cursor in the story, choose Edit > Select All. With the entire story selected, change your Keep Options (Type > Paragraph > Paragraph panel menu) to look exactly like this:
When you click OK, is the rest of the story visible?
If not, please enable Type > Show Hidden Characters and share a screen shot of story editor view with the overset line visible so that we can see what follows the line.
