I have no clue what could be causing it, I've heard various things from my car sucks and it's old to something called vapor lock in the fuel lines.

Any other problems or noises? Does the car falter or try to die but catch any other time? Does it have A/C?

The car has A/C, I have noticed that when the engine is warm, the tachometer shows that the RPM will go up to about 1100 when you first start it, then drop considerably, almost to 500 (which on my tachometer the min. Measurable rpm is 500 before it goes to zero. And then it will settle down at 750, which is normal idle speed +/- 50 rpm. It revs higher when the lights are on or the a/c is on, but that I think is normal since the a/c and lights require more power. This is really the first time it has stalled since I fixed the problem with the main relay. When it did stall, it was on a slight to medium incline in a parking spot, the engine was warm (I had stopped in a bookstore for about a half hour), and when I started it up, it fired immediately (Almost never a problem) and immediately died. I tried again, making sure to keep the starter engaged until the car started, thinking I brought the key back too soon, but that didn't work. I tried two more times and on the fourth try I gave it some gas as soon as it started and it was fine until I let off, then it almost died, but came back to life. I have been driving it around a lot lately, about 200-300 miles per week, but on that day and the day before I had driven it 50 miles. Any clue as to what it can be? I heard it might just be because the car is old, but wouldn't fire right back up the second time?

As far as I can tell the only problem with the car other than a few electrical luxuries such as the cruise, two power windows, and a few wiggling fuel and speed gauges, the only other noise I hear comes from a belt, but only when the car is idling at or below 750, Haven't identified which belt it is, but it isn't that loud. A few times when I shut the car off, something which I think was the catalytic converter was making a low tone or some sort of noise I can't really put words to. I actually recorded the sound if you need to hear it, but I haven't heard it since the new exhaust pipes were put on. I certainly hope nothing serious is wrong with this car, considering I just put new motor mounts in, as well as a new radiator and exhaust pipes.

Does anyone know what could be causing this? IT happened again twice in the past week, and it never used to stall since the main relay was re soldered
