How do you keep a conversation going?

I have a problem with talking to people. whether its someone i just met of someone I’ve known my whole life, I just can’t seem to keep a conversation going. I usually have two backup questions to use incase the conversation starts to slow down a bit, but after that I’m lost. I just don’t know what it is about me.

do other people have the same problem too?
what do you try to do?
