Engine runs fine till it warms up then cuts right out and gives a PO440 code and will not start for hours
SOURCE: VW Polo 1998 Model runs fine for about 5 km
check all vacume hoses for splits.this sounds also like air being drawn from the fuel tank sender unit which could be corroded.is there a strong smell of fuel inside the car?this could also be a secondary jet being blocked in the carb if it has one.good luck

it starts from cold because the auto choke is on ,allowing a richer mixture ,try removing the sender unit in the tank and seeing if the connection from the pump to the outlet connection is ok or leaking causing a loss of fuel pressure

you must hook up a scanner to the obdii connector when it fails read codes
Testimonial: "you're probably right but I don't have a scanner Thanks!"

Did you ever get to the bottom of this problem? My car has the same codes- dealer says it might be the fuel pump relay. Wondering what you found out?
This indicates that a part of the EVAP control system is no longer fuctioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
