Aha, to me it seems like your fuel system is losing pressure at some point. I've seen it with other turbo cars plenty of times. Also- the fuel injectors and coil packs on these cars go bad pretty often as well. Have you tested them out? Any codes being thrown?

Have all hoses, rails, and bolts been checked for proper pressure seals?
