Default Needing some advice

Okay trying to figure out whats wrong with my car, took it out to go get it inspected last week and on the way there it was sputtering at like 3,000 rpms, the plugs are only a month old so i was figured maybe they just need a little clearing out so I got into just to see if it would.
Drove it for 10 mins and went to push cluth in and the car just shut off and would not start back up. But it would start the next day when i moved it into the garage
I assummed it was the fuel pump even though it was pretty new itself, I went ahead and put the same racetronix fuel pump back in and fired it up and it idled and revved up fine, went to take it out of the driveway pushed in cluth and it died again and wouldnt start again.
Suggestions or ideas on what would cause this?
also it is throwing no codes and i efi swap on it

It's only when your pushing in the clutch?

I'm not sure if your neutral safety switch will cause your car to die when it goes bad... But I know it'll keep your car from starting

^ Valid point. Id look into replacing it. It might be shorting out and causing your car to die.

I'd check the fuel pressure.

After you start it, can you rev it up, or is it stuttering in neutral?

Also, since your first thought was spark, I'd check the coil & the opti.

okay so a few of yall suggested the neutral safety switch, so i replaced that and my fuel filter, it started up and idled fine, drove it up and down the driveway a few times and figured it was worth testing on road, went to pull out of driveway, its a little bump pulling out and it did the same thing just instantly dies, my fuel pressure is holding steady at 44psi..
so now what?

Interesting... If you let her warm up and go into closed loop does it throw any codes?
