what causes car to stall after driving 8-10 miles? on 1997 Honda CR-V

It runs great except for the stalling. we have had 2 oxygen sensors replaced,catlytic converter replaced, throttle body cleaned out, switch replaced, coil replaced, check engine light is still on and still stalls and will not take gas like it should.

It could be so many things and tough to guess without being able to do basic diagnostic tests. Your car has On Board Diagnostics (OBD2). A 16 pin diagnostic socket under the dash allows a scan tool to be attached to interrogate the on board computer in your car. A professional grade scan tool reads stored trouble codes, pending trouble codes, looks at live sensor data so you can look at a sensors performance and output signals without having to do intensive testing at each sensor, (cheaper scan tools have limited capabilities and may only read the trouble code stored). As with most things automotive it's best to check the basics first, check for vacuum leaks, fuel pressure and delivery volume. Verify engine mechanical integrity before looking for complex problems check that the basics are sound. People over look valve clearance on that engine and the valves burn out! The fuel pump relay fails and more important the ignition switch electrical portion fails and causes stalling (call Honda with your VIN # and see if the recall has been done. Next time the car stalls bias the ignition key in the switch a little toward the starter position and see if the engine will stay running. You would need a wiring diagram and test procedures, perhaps a fuel pressure gauge and instructions to test the distributor pick ups (they also fail intermittently on that year/model). This is a simple car should not be hard to figure out what is wrong.

possible fuel pump....a mechanic can hook up a fuel pressure gauge and drive the car ten miles....if it starts to stall....he can look at the fuel pressure...if it drops its the pump
