Trouble starting my Rincon

What does this mean? Is this sticky idle air control valve or something related? It starts and runs fine for a couple minutes then suddenly dies... Then again starts immediately after dying but then dies again. If you kinda hold the throttle open, it's running smoothly. Please, any insight would do.
 
That could be a problem with your idle air control valve, but starting right back up after dying makes me think it could also be a fuel delivery issue!
Have you also checked your fuel filter or fuel pump pressure?
 
You might be onto something with the IAC valve and fuel delivery. Since it restarts right after shutting off, I think it could be a fuel problem too.

A quick test for fuel pressure and checking for any error codes should help figure it out.
 
It could also be a vacuum leak or maybe a fuel delivery issue causing the stalling after warm up. Checking hoses for leaks and fuel pressure might help see the problem alongside the idle air control valve
 
YOu already got the usual suspect here, so I'll give you another one, the throttle position sensor. The good news is that you can check if it's working with a multimeter. Check the voltage and the resistance and make sure they're within operating range specified by honda.

I agree with this one. it sounds like an IAC valve issue, or potentially a vacuum leak somewhere after the throttle body
If the IAC isn't opening properly at idle, or if there's an uncontrolled air leak, the engine isn't getting enough air to maintain combustion when the throttle is closed. Holding the throttle open manually compensates for this. I'd start by cleaning the IAC thoroughly and inspecting all vacuum lines for cracks or loose connections
