thank you. As you mentioned, I understood that I am starting the streaming scratch which is not what I wanted to do.
Here is what I am planning to .
Our replication process was down since March5th.
1. Is it Ok to get all wals from March5th till now to standby pg_xlog
2. take pg_basebackup
3. export the data dir
4. stop backup
5. restart the standby.
Based on my understanding it should work, because when standby started, it is not able find the files, as I have deleted from the slave them when I tried to fix the issue

That process merely sets up a new server, it doesn't start streaming,
unless the server has been configured correctly. You state that the
slave crashed after two hours. How did you make this determination?
All you seem to be doing is setting up the slave from scratch
repeatedly, and assuming that it will magically just work, rather than
understanding & debugging why its not working. Where is the log
output from your servers that shows what is really transpiring?
