Question 2008 Ninja issue

Hi there,
I was wondering if anybody has ever had the problem with their ninja 250 like I do now
The bike starts, when in idle runs for a minute or two and then it dies. When I keep the revs up, it's ok.
It doesn't sound like it used to, sounds more muffled and dry.
Also, when I drive it in that condition, the bike is pulling, sort of like if it didn't have any fuel left.
There was a white smoke going out of the exhaust for like a few seconds as well.
I will take off the tank and see if it has anything to do with the throttle.
Any ideas? I would appreciate any suggestions!
Thank you!

Have you checked the condition of the air filter and airbox for oil?

Is the tank clean inside? Have you checked the filter at the carb inlet?

Have the carbs been synced, and idle mixture and idle speed adjusted?

Have the valve clearances been checked recently?

How old is the gas?

White smoke is not good sign. What’s it smell like?

Do you have choke turned off after first couple minutes?

Do compression-test when you get chance.
