2005 Artic Cat 400. Starts fine runs fine but after 5 min seems to run itself out of gas. Wait a couple minutes and starts right back. Could this be carburetor or something else?

1. Carburetor: Inspect the carburetor for any clogs or dirt buildup that could be affecting fuel flow. Clean or rebuild the carburetor if necessary.
2. Fuel Filter: Check the fuel filter for clogs. A clogged filter could restrict fuel flow and cause the engine to run poorly.
3. Fuel Lines: Examine the fuel lines for any kinks, cracks, or leaks that might be disrupting fuel delivery.
4. Fuel Pump: Test the fuel pump’s functionality. If it’s not providing a consistent flow of fuel, it could lead to the issue you’re experiencing.
5. Air Filter: Ensure the air filter is clean and not clogged. A dirty air filter can affect the air-fuel mixture and engine performance.
6. Spark Plug: Check the spark plug for fouling or wear. A worn-out spark plug can lead to poor combustion and engine problems.
7. Venting: Make sure the gas tank is properly vented. A vacuum in the tank can cause fuel delivery issues.
8. Ignition System: Inspect the ignition components, such as the ignition coil and spark plug wires, to ensure they are functioning correctly.
9. Idle Adjustment: Check the idle speed and air-fuel mixture settings. Incorrect settings can cause the engine to stall or run poorly.
10. Cooling System: Ensure the engine is not overheating. Overheating can cause engine problems, including poor performance.
11. Exhaust System: Check for any exhaust restrictions that could be affecting engine performance.
12. Electrical Connections: Inspect all electrical connections for corrosion or damage that could be affecting sensors and components.

By systematically checking these components, you might be able to pinpoint the issue causing the symptoms you described. If you’re not comfortable with these checks, it might still be a good idea to consult with a knowledgeable friend or a mechanic.
