Your problem is indeed intriguing.
I in recent days discovered something possibly of note for you, but
probably not - I've been using mail.google.com in firefox, and would
swap between two different computers in my house, which would work,
then one day it stopped working, as in, I'd use email on one computer,
then email would not work on the other computer. I was proxying
through a vpn though, to another computer on a different external IP
address, and after some time I figured this out. It seems google uses
some server cookie binding client login to ip address (which in
hindsight is a sensible security choice), and that if I had have
logged out of gmail on first IP address/pc, then logged in on
laternate ip/pc, then google probably would have been ok with that.

Possibly worth testing your MUA kmail with an strace log file, and
view the end of that log as soon as you notice the POP/IMAP stall.
Possibly set up another email account with say yahoo or use your isp
email account (eg forwarding/copying all your gmail email, so that you
know it will have email in it of some sort) and test picking up email
from this new account, immediately after, and only after, you find the
gmail pop/imap stops working (so you know there is email in there to
pick up).

Because of your high occurrence latency, you might set up two or three
of these alternate accounts, but at least one alternate account would
hint at whether it is possibly limited to being protocol (pop/imap) /
MUA related (and therefore a client side issue), or email server
specific (gmail).
Good luck
