Still sounds like a fuel problem. Try a full tank of supreme gas, plus put a can of SEAFOAM into the tank to help clean you injectors. See if this will help clear up your problem. Did you change the plugwires????

SOURCE: 1997 Geo Metro Stalling
After driving for a while and the engine becomes hot, when you park the car for a while, does this "for a while" mean enough time for the engine to cool down or not?
The reason why this is important is because an engine can stall for a number of reasons, and finding out the conditions of its stalling obviously helps narrow down the cause of the stall.
If it stalls, you say, when the engine cools down after being parked for a while, this handy diagnostic article will help assess the cause of your problem:
If it stalls again, like you said, after warming up and driving for a bit, the ambient temperature may be too as well as the engine itself, which then you should be inclinde to read this diagnostic article:
You may very well be right its due to fuel starvation, particularly as to the malfunctioning of the EGR, as noted in the article.
I'm sure these articles will provide you with great insight.

It seems the starter is playing up.First check if your battery is charged fully or try to jump start and see what happens.If the engine start then it's either you need a new battery or else you need a replacement alternator.Test using a voltmeter if the actual altenator is working.Finally the last option is the starter motor that needs changing or fixing...Hope this helps.

A fuel pump would cost around three to five hundred dollars, you have to drop the gas tank to replace. i would condsider making sure that is the problem. You should have the fuel pressure tested, you may have another problem. I would make sure you dont have a vacuum leak, misfire, or other causes idle air control pintle could be sticking due to contamination and depending on the engine a bad mass airflow sensor. Do you have a check engine light on if so go to autozone have them read the codes and post back. Alot of mechanics always go straight for the fuel filter and it almost never is the problem.

I realise you have probably solved this problem by now so sorry for the late news mate . Had a similar prob and it turned out to be an alternator malfunction . I replace the brushes and off she went . These things send voltage from the alt . to a fuel pump relay or whatever so the pump wont run if the eng isn't (or the alt isn't outputting any voltage.) . Hope you already had it sorted . But I hope this helps if not . Cheers Simon .

· Fuel Pump secondary circuit shorted to power
· Fuel pump relay contacts always closed
· Open in fuel pump monitor (FPM) circuit between ECU and connection to POWER TO PUMP circuit
· Heated Exhaust Gas Oxygen (HEGO) sensor shorted to power
· faulty ECU
Engine Does Not Start:
· Open inertia switch or inertia switch circuit
· Open in or between ECU and fuel pump (This includes open in fuel pump brushes/windings)
· faulty ground connection at fuel pump
The easiest way to check this circuit is to go to the fuel pump relay. If the relay clicks when the key is turned to the "RUN" position, then the inertia switch circuit is ok.
The Pink/Black wire starts from the fuel pump relay and goes two directions. One side goes back to the fuel pump. The other side is the fuel pump monitor circuit and goes to pin #8 at the ECU. This wire should only be hot for a second or two when the ignition is turned to the RUN position.
The fuel pump relay receives power on the Black/yellow wire. It comes from a fusible link at the power distribution center. This wire should be hot at all times.
If all the above is working as designed, them you probably have a bad fuel pump.
