I have a similar problem, but I am still poking at it. I suspect in my case
that it is the Annex terminal servers playing up.

At first, I thought nothing was coming back in my case. But it turns out
that all the pings (to a machine two hops away from my remote PPP connection)
do eventually come back. But the IP connection freezes for an indeterminate
time: sometimes 20 minutes, sometimes two hours! You might find the same
thing in your case if you leave the connection up with a ping running, sending
out an ICMP echo-request every minute or two. (Or you may not :-)

Yes, large ftp transfers often trigger my problem, too.

A PPP troubleshooting guide would be a good thing. Any volunteers?
Preferably somebody whose PPP connection is actually working :-)
