Durante a diagramação o arquivo se fecha sozinho sempre na mesma página

If there's a placed graphic on the affected page, move the related graphic from its current storage space to the computer desktop. That will cause InDesign to fire an alert that the graphic is "missing", but won't let the program link to what I suspect is a problematic graphic.

If the diagram is placed inline with the text you're placing (e.g. - it's integral to the document and was inserted into the text in its originating application), go back to the originating document in its source application, use File>Save As to duplicate the file under another filename, and then try to place the document in the chapter without the diagram.

That will let you determine whether the diagram itself is causing the issue (most likely), or if you're chasing down a blind alley and there's an extraneous factor that hasn't been considered which is causing the problem. If it is the diagram, perhaps you can extract it and place it into your InDesign file using another avenue to get past the problem.

Please give this a try and let us know how things work. From there, we can better advise you how to avert the problem.

Hope this helps,

Randy
