I'm new and I need help. :(

Hey everyone--I'm new this forum, so hello. I am hoping that somebody will have some suggestions on how to remedy my problem...Well, last summer my 95 240sx with stock KA engine started acting up. I was driving down the road and it just shut off--no sputter or indicator lights. After I would let it sit and seemingly cool down for about an hour, it would run again and then do the same thing. It took me 2 hours to get 15 miles. Brought it home and ran a scan--knock sensor came up bad (which I heard can be thrown off by other issues) and I replaced it. Also replaced spark plugs and wires, water pump, thermostat, coolant temp sensor and got a new distributor thinking that it might be the sensor inside. Still nothing and I am getting really frustrated. I really need to get this thing in top shape in the next 3 weeks so any ideas at all would be an amazing help. Thanks so much everyone!

Unplug your injectors one at a time, the rpm drop should be the same for each injector. If you unplug one injector and notice no difference, it needs to be replaced.

Dunno....

replace your coil if its not an internal coil style. when coils get hot the contacts inside seperate but when they cool back down they can work again.

does it shut down when you're trying to slow down with (coasting to a stop or with your foot of the throttle)?
