Anyone have any ideas why power loss can occur while driving for no apparent reason? Timing jump? Sensor? Ignition?

 

vacum connections, air filter, oil pressure, umm........ does it do it while turning or just driving straight down the road? MAS, are the turbos working properly......., my gf had a turbo and she had a blockage in the air filter, every time the turbo tried to give boost the car stalled......
