i had a similar problem with my protege with what felt like fuel cut but it was actually the engine sputtering and what it was, was the manifold bolts holding the turbo and manifold together had loosened and there was a huge seperation causing loud turbo noises and compressor surge the super sequential sound the problem worsened because they just kept backing out, also again i had what i thought was a similar problem but it happened to be a bad coil pack which should throw a check engine light to notify you which pack to change because your car has 2 of them
ps if your checkin your manifold yourself it isnt always just looking under the hood the heat sheild has to be removed but not just that my seperation was in the back side so just looking in the front didnt work you can take a mirror kinda like the ones dentists use they sell them at your local parts store and look in the back a sure sign will be easily seen seperation or harder to see carbon build up (black) on the engine block or on the turbo
good luck
