Hello im fadli from indonesia..

I bought a 2000 spacewagon 2.4 gdi last october. It has been running fine since except in the last two weeks the car has been losing power while driving and going into limp mode. It can happen after a long or short drive with no warning. The power will drop and the engine management light will come on ( if I try to accelerate light will go off but stays in limp mode). If I pull over and stop the car and turn everything off it will drive again for Another while then do the same again.
DIAGNOSTICS didnt show up anything other than fuel system.
Changed the fuel filter and now nothing coming up on diagnostic but still the same problem.

i was changed gdi pump(high pressure), injector, o2 sensor, fuel pump in tank (low press)

but the problem still same

Anyone experienced similar or have any ideas?
