Car dies when in drive

[SRTFerg]

Hello all. I recently purchased a 95 240sx. Sadly it is an auto but I have all the parts required for the manual swap and willl be doing the swap once i can get the car to the garage. A few days ago I was on my way to a friends house when all of a sudden the car wanted to die unless I gave it gas. So I rushed it to the house where it died upon parking. When I try and start the car it will not start on its own unless I mash the gas down. Once started it will run and idle fine until I go to put it in drive and then it just dies. I can hear the fuel pump turning on. I have also replaced the fuel filter, plugs, cap and rotor and still nothing. I need to get the car running soon so I can get it to the garage for my swap. Any help or imput would be appreciated.
