sounds pretty normal. what speed do you try out the passing gear? anything above 35-45 mph and it will feel like neutral. Passing gear is actually only 1st gear. When you press down the pedal, it forces the transmisson to shift into low gear.

either you have a worn electric fuel pump which can't make enough pressure or a clogged fuel filter and thus dirty fuel system.first use a super cocentrated injector and fuel system cleaner from a reputable brand if unsolved you should seek pro diagnostic and repair.
