Sorry for the time !
With 6.0-pre0-3737, i have the same problem. It happen always at the same timing, regardless the buffersize.

I downloaded the session, tested with 6.0-pre0-3766 ... i am missing 5 plugins ... no issues looping here.
Please run in safe mode ("disable all plugins") and see if works.

After tests with Ardour pre1, I got the silence watever the plugins enable, the buffersize, the output via alsa or jack... On two computers running debian SID and Testing.
The problem happen a little bit before the middle of the first loop.
I belive that x42 have already work on a similar issue (via IRC).

Attached two screen of the recorded output via jack.
On the second one we can see a correctly declicked output.

After other tests, it seem that the problem disapear after i move the loop markers, but reapear if i disable/enable the loop mode (with "The loop button is a play mode" option enable)

Another thing : when the silence happen, i see alls the vu-meters falling, so it seem to me that the problem happen at the input of the tracks or at the file reading.
