You are assuming that date is in your path by the above statement.  Never 
assume you have a good path, unless you set it in your script file.  So, 
either setup the path you need or use absolute pathnames such as:
TIMESTAMP=`/bin/date "+%Y%m%d-%H%M%S"`

Make sure your script runs correctly outside cron, then test it from inside 
cron.  Add some echo statements so you can see what is executed, such as:
#!/bin/sh
TIMESTAMP=`/bin/date "+%Y%m%d-%H%M%S"`
LOGPATH="/home/pjn/parseGP/logs"
echo $(TIMESTAMP)
echo $(LOGPATH)
echo /usr/local/bin/wget --no-cache -a ${LOGPATH}/fetch.log -O
/usr/local/bin/wget --no-cache -a ${LOGPATH}/fetch.log -O
echo ${LOGPATH}/${TIMESTAMP}.html http://www.blahblah.com
${LOGPATH}/${TIMESTAMP}.html http://www.blahblah.com
