Netsuite - REST API (restlet)- creating record causes INVALID_LOGIN_ATTEMPT failure on the 2nd and more request for records

I have problems creating subsequent records with netsuite rest api using Token Based Authentication (TBA) oauth authentication. Here is my full code: https://gist.github.com/axilaris/428e63e5ff107d212fbcc07c5bdbce7a (it contains restlet, python code and the output of the python code).

The first record get created (you could see success) but the 2nd always get INVALID_LOGIN_ATTEMPT. If I remove creating the 2nd record, it will still be successful creating each time. But if I have in a process creating 2nd or more, its always the 2nd and more will have INVALID_LOGIN_ATTEMPT.

Can someone advise is authentication TBA required each time creating a record ? Is there a better way to handle this by doing TBA authentication first and then using that response (possibly a token) for creating multiple records ? Please advise as I have a platform that regularly creates records.
