honda gx620 20 hp v twin engine stalling problem

I have a Honda GX 620 20HP v twin engine on my side by side that idles perfectly, but when we drive it, after a few minutes it bogs down and dies.  It will start right back up with the choke pulled, but dies after a little driving.  We have replaced the carburetor, fuel lines, fuel filter, and spark plugs.  Can anyone tell me where to look from here

Are both cylinders working? Have you tried removing fuel cap off tank?

I have loosened the gas cap. It will run fine sometimes fo 30 to 40 minutes, then starts bogging down and dieing, starts right back up with choke pulled

Fuel tank doesn't have debris in it? If the fuel filter is the clear one, does fuel level drop in it when this happens? I have to leave town so I haven't had a chance to look up the engine.

We cleaned out the fuel tank before we replaced the carburetor anf fuel filter. I have not checked the fuel filter when it dies. Thank you for your help, i am getting frustrated because my grand daughters want to ride

Take some carb cleaner or starting fluid and spray into carb when it starts bogging down.

The carb is less than a week old, it hasnt had enough gas through it to be dirty

My post was to see if you have a fuel delivery problem. If you use the carb cleaner or starting fluid while it's bogging out and rpms increase and it starts smoothing out. Then there is a fuel delivery problem. Diagnosing only, wasn't implying your carb is dirty.

Sorry, i didnt know what effect you were looking for with the carb cleaner. I will try that tomorrow. I know nothing about engines and i am trying to not take it to a shop. It idles perfect when first started and for anywhere fron 10 to 30 minutes after first started. I apologize for my lack of knowledge

Not a problem, we have to have fuel, compression, spark, and timing to keep it running.

Hi Mike, we finally figured it out. It was the oil safety switch. Thank you again for your help

Yep that was next, not many things affect both cylinders at the same time.
Glad you got it figured out, your granddaughters will be happy.
