When the connection fails do a ps -uax | grep pppd and look 
for the ppp process, then do a kill -9 PID# of pppd. Or look 
in /var/run and see if the pid # of the pppd process is there 
and try killing it before starting the connection sequence again.

pppd doesn't like to die when the connection fails. I've got a 
script that will do this that i run continuously from a cron 
process to keep my ppp connection going:

#!/bin/sh
PATH=/etc:/bin:/usr/bin:/sbin:/usr/sbin:/usr/local/bin 
LOGFILE=/var/log/ppp.log
export PATH LOGFILE

if [ `ping -c 5 PPP_PROVIDER | grep "packet loss" | awk '{ 
print $4 }'` -eq 0 ] ;then
        kill `cat /var/run/ppp0.pid`
        sleep 15
        /etc/ppplogin
        datestamp=`date "+%b %e %H:%M:%S"`
        host=`hostname`
        echo "$datestamp $host $0[$$]: pppd restarted" >> $LOGFILE
fi
exit
