Lately I have a problem where the ppp connection goes down. 
Watching the log I see the following;

I shutdown ppp and restart it with no luck.  I shutoff modem and 
reboot it and wait for connection light to go solid - still no go. 

I called ISP and they say there is no problem.
I try to login to the ISP with a windows box and am successful.

Having no luck connecting with my server, I reboot, and all is fine. 

What could it be about rebooting the server that allows connection
where otherwise it is not possible?

Any ideas where I can look for answers?

my ppp.conf follows;

default: # or name_of_service_provider
      set device PPPoE:fxp0 # replace xl1 with your ethernet device
      set mru 1492
      set mtu 1492
      set authname ***********
      set authkey ***********
      set log Phase tun command # you can add more detailed logging if you wish
      disable ipv6cp
      set dial
      set login
      set ifaddr 209.161.205.12 206.221.248.4
      set ifaddr 10.0.0.1/0 10.0.0.2/0
      add default HISADDR
      nat enable yes
