Ok it runs like a horse around town and on short trips on the highway. But after 50 Km if highspeed driving the engine stalls out...it will idle but it you give it gas nothing happends at all...like the engine id turned off...
At this point if it stalls it won't restart....

If I stop and shut off for 10 minutes , or pull the battery for 30 seconds then the car restarts and runs great for another 40-50 kms then it starts again.

no error codes can be found (maybe becuase of the bettery removeal)

the rest of the time it runs like a dream and always starts...


Any ideas where to start looking???

Thanks
