I can't reproduce this on FreeBSD-4.2 with the just-released bash-2.05
using job identifiers:

nike.ins.cwru.edu(3)$ ls -alR / >/dev/null 2>&1 &
[1] 61036
nike.ins.cwru.edu(3)$ kill -STOP %1
nike.ins.cwru.edu(3)$ jobs
[1]+  Stopped                 /bin/ls -F -alR / >/dev/null 2>&1
nike.ins.cwru.edu(3)$ kill -CONT %1
nike.ins.cwru.edu(3)$ jobs
[1]+  Running                 /bin/ls -F -alR / >/dev/null 2>&1 &

or on Red Hat 7.0 with the same bash version:

caleb.ins.cwru.edu(3)$ ls -alR / >/dev/null 2>&1 &
[1] 24443
caleb.ins.cwru.edu(3)$ kill -STOP %1
caleb.ins.cwru.edu(3)$ jobs
[1]+  Stopped                 /bin/ls -F -alR / >/dev/null 2>&1
caleb.ins.cwru.edu(3)$ kill -CONT %1
caleb.ins.cwru.edu(3)$ jobs
[1]+  Running                 /bin/ls -F -alR / >/dev/null 2>&1 &

but I can reproduce it using pids.  My advice is to use job ids until
I can figure out what the problem is.
