There has been a few cases of engine failures at Camerons. One cause is a faulty fuel pump.
It could also be due to a faulty air quality sensor. Which may be your case. As you go higher, air density decreases. This tends to make the air/fuel mixture rich. Combustion is not sustainable beyond a certain ratio,ie too rich, and the engine will initially shake and eventually shut down.
The engine may start after a few cranks, as the rich mixture is blown away through the exhaust. But the engine will vibrate and misfire cos the existing air entering the cylinders at that height is low on density. ECU is not getting the correct air density feedback to make fuel adjustment.
Once you come back to lower ground, engine runs normally as it's getting the right air/fuel mixture due to correct air density. The failure messages disappear.
Thanks for the info skyjack, I called the SC and they said they will able to check the error even if it disappears.
But if they cant find the error, how to fight against them? I told this to the sales person and she said I muz put ron 97 atleast once a month.

. I laughed...and said how can this solve a severe problem to the engine. and she said because my car mite have excessive carbons. they are giving their own reason....aduh. Have to put a scene at SC and make them rectify the prob.
