I have a 2005 and after it runs for approx 2 min it dies. I turn the fuel off, purge the inlet hose from tank, turn back on and it fires up and runs awesome then dies again after 2 min or so. I’ve cleaned the carb thoroughly so I know it’s not a plugged vent line. Does it with or without cap on the tank. Anything else I can check?

I put carb cleaner and compressed air through every single orifice In the carb. Jets are cleaned with tip cleaner. Blew backwards through the tank vent to make sure it's not the tank that's vapor locked. Even rode around with the cap off.
Have you done an ohms test on the ignition coil on both the primary and secondary sides. If so, what were the readings? A coil can break down even with showing a good spark at start up. When this happens your loose spark then when the coil cools down the spark will return.

Yes I replied to your first response lastnight, thank you. When you say ohm out the coil, are we looking for a resistance measurement or just continuity across the circuit? I will ohm our the ignition, but I still feel it’s fuel related. The second I relieve the head pressure from the carb inlet, it starts first kick. I have it down to where it only is dead for 5 seconds. Lol. Thanks in advance!
RE: coil....Yes the resistance readings.

I will also put my meter on the bike and ride around and see what’s happening voltage wise when it dies.
For trouble shooting purposes, I guess I could pull my carb off my cr and see how it acts on the bike. Process of elimination.
Also check that coil.
Also pull the fuel petcock and check the filter screen on it.

So as soon as the float filled the bowl, the seat moved down with the valve and wouldn't let more fuel in until I pulled the fuel line off, and it got a gulp of air to reset the float and fill the bowl again.
