92 240 with a stock KA. Motor randomly dies. Help required.

I made a post about this, but let me summarize it up real quick.

Bought a 92 240 for a great price cause the motor dies randomly

I've had it for a month and it died on me today on the road.

The car: 92 KA 240sx. New plugs, new wires, amongst other tune up things.The car was full of premium fuel when the motor died.

I'd been riding around all day running errands no problems. I leave the store, and I'm at a stop sign. I start off like normal, and shift into second and the motor died out of no where. No sputter, nothing. rpm drops and the lights on the cluster come on.

I try to crank it and it wouldn't turn over. I crank for about 3-5 mins and it just won't turn over. Finally it starts grabbing a little and I'm mashing the gas pedal and it finally catches.

When it catches it's almost about to die, and i'm getting bad throttle response, and it's sputtering like it's missing a cylinder. I keep the RPMS up and the motor stays alive. After 30-45 seconds of keeping the rpms up it starts to hold an idle and i'm able to drive it to a parking spot.

I had a similar issue with my old civic before and it turned out to be a distributor.

THe previous owner says he's replaced the distributor, but I'm affraid he may of just gotten cap and rotor or something. I'm thinking it could also be a coil as well.

I tried to turn the car on afterwards and it turned over just fine.

I replaced the fuel filter (put in a z32 filter) when I did my tune up, i'm not thinking fuel cause if it missing on fuel it wouldn't of died so quickly. The motor would of hesitated when it dieing. My gut is telling me distributor.

Any help is greatly appreciated.

Mas Air Flow Sensor may be going out, test it . or mabey even Throttle Position Sensor, test it too.

i pulled the MAF when i put in new air filter. looked great. no issues.

i'll check tps but if it was messing up if notice something in normal driving, it can't just die randomly. can it?

when the motor died. it was as if someone turned the key to the off position. it died completely and very quickly.

It's not likely the TPS: you car will still drive even with it completely disconnected(although only rev to 2000rpm if I recall correctly). My '90 Accord had a slowly-dying coil pack, and it did the same thing. Other than that, possibly the fuel pump, although when they are bad enough to just quit, they 'stay quit'.

BTW, it may be worth it to clear your ECM of codes, then re-check after it dies a few times(ie once you get home)

Wiggle the plugs at the injectors. See if that does anything for you. If that don't do it, I'd suggest bringing out a multimeter and start testing a few things, but first do the wiggle test.

So it happened again.

I was driving and it randomly just shut up. Out of no where, and very clean cut off as well. No hesitation or any inkling it was going to die. It just died.

I let her sit for about a minute, I got her to turn over and I was able to drive her back home. I have no idea what's going on.

Any help is greatly appreciated.

Sounds like something up with your ignition coil/distributor or fuel pump. Lets start off with the ignition coil though. You'll need a multimeter for this.
