Hope someone can help please? 2000 3.0lt sw,22000 miles, outback wagon mint condition, drives great around town on short trips. But after about45 - 50 min driving I get a flash of the engine light and the engine faulters momentarily [ less than 1/2 second ]. 5 min later there will a similar occurrence then progressively the time intervals between flashes/engine cut reduces to the point where the light is on contiuously and engine is dead. After 10 - 15 cool down period I am able to start engine and continue for about 5 min before the above dreaded light starts its cycle all over again. I have connected my OBD II tester and no fault codes display. Can any body help Please?
