Is there a limitation how much content in a session

I have been using one session for asking so many questions typically fine tuning my interview questions. I am sure it is now 60 or 70 questions and its responses. I have attached so much content to be relevant. I am sure my session is almost 80 to 100 pages long. I am facing following issues

  1. responses are not accurate
  2. responses are not generating or stays blank response
    My question to the community is, is there a limitation on how much content or length of the session?
    Any tricks to overcome this?

I got an error finally, that indicates there is a limit. But way before this message, GPT was very inconsistent.
