Your ssh session needs a controlling terminal, for that use ssh -t

Also, you can execute part2 from ssh directly. So part1 will look like this:

**SCRIPT1**
#!/bin/bash

target_server="1.2.3.4"
target_script="/home/user/script2.sh"

echo "Script 1 Started"

scp $target_script $target_server:/tmp/my_script_part2.sh
ssh -t $target_server /tmp/my_script_part2.sh
ssh $target_server rm -f /tmp/my_script_part2.sh

echo "Script 1 Ended"
