If you add before starttext \interlinepenalty=10000 it works. But alas, not in my case.

This will change the settings for all paragraphs while \keeplinestogether

only applies for a given number of line for the next paragraph.

That is exactly what I want: keeping all my paragraphs together. But when I use it in my file, I get a few lines pro page.
