Well, when I was driving my rpm started going up and down. I pulled over on the highway, popped my hood to check. Man, the engine started shaking pretty hard and then it died. Started checking everything. Waited thirty minutes and cranked it and started up fine untill it was warmed up for like a minute or two then rpm went up and down again and died. I thought it was my MAF sensor because it did have some missfire, my temp. Coolant sensor too. Still the same. Have new ngk plugs and new stock wires. Tried a vaccuum leak cheak, none leaking. Now I'm thinking about the ignition coil. Haven't tried yet, because it's new. Might have to check the voltage I guess. So if you can help me out, thanks. Don't want to spend money on what is still working fine.
Do you

Check the fuel pressure to rule out the fuel pump if okay recheck the ignition system.

Could it be something with my timing? I may have to change that out. One of my buddys I remembered had like a similiar problem too. But I'm not sure so let me know. It starts up fine when cold, but just dies when warmed up. I tried my ignition coil, module already too. Still same thing. Can the fuel pump have a leak somewhere? If it is the pump wouldn't the car not even start though? But yeah I'm going to bring it to a shop down the street so. Thanks.

My buddy had replaced his timing chain and it ran perfect. It's weird, but it may be it.

Okay I took my car for a diagnostic test. They found two codes, but my engine light wasn't even on. That's weird. Isn't suppose to come on for a code. Oh well. Well the mechanic guy said it may be a crankshaft sensor or a ignition switch causing the problem. They said that the crankshaft maybe the problem that causes for the igniton switch code to pop up too. But Ima go ahead and try the crankshaft sensor first then. Then the igniton switch.

Okay, I'm not sure if the crank sensor is inside of the distributor or not on my 92 240sx. I know 95 240sx isn't. The mechanic said that it was my crank sensor or ignition. Ima go ahead and replace the whole distributor and see what happens. I hope it works.

Well, it was my crank sensor inside of my distributor. I just went ahead and bought a brand new reamnufactured distributor and it cranked right up. Thanks dude for helping me.
