I would have to say the engine timing is off because it revs up to 3k then dies. if your car should have some kind of engine warmer, look on the dash for some sort of spiral light or something that likes up then goes away after a few seconds of the key being turned.
You should be able to use the same drive shafts provided that you only are rising the body higher that the wheels. Think of it like a monster truck, the body is really high but the drive shaft and everything else says in place.
As long as your not pulling it like 40 ft out of the water it should be fine cuz i pull my boat out of the water and onto the trailer which is about half submerged and it comes out fine so you should be fine especially cuz its full time AWD.
