Unhappy Losing Throttle After Riding for 30+ Mins

Hey Guys, I'm a fairly new rider and recently bought 09 Ninja 250. The bike has about 785 miles which most likely mean that it sat in a garage for awhile.

It rides fine at first but usually after 30 mins, especially in city driving, where I have to use first gear a lot it tends to lose throttle response. I kick it into first, the idle would drop to 1K (from 3K) and when I give it gas it just stays idle at 1K then eventually dies.

I restart the bike and it's fine for a bit then the issue comes back shortly after.
Sometimes, I shut the bike for about 10 mins or so then it works fine after wards and usually I can make home, not sure if something could be overheating.

I'm planning to take it to a local shop soon but wanted to know if you guys have insights on what the problem could be. Thanks!

Seems like the bike is having some problem with either the ignition or fuel system.
