Hi,

It is probably electrical because it goes away when it cools down. First you should diagnose if it is a fuel or ignition fault. When the car is dead, see if you are getting fuel and spark to the cylinders: remove a spark plug, but leave it on the wire and rest the plug threads on a metal part on the engine, and have someone crank the engine - look for a spark. Do not hold the spark plug or you can get a shock.

If you are getting no spark, the problem is the ignition control module which is located under the distributor cap - the round plastic piece from which the spark plug wires run.

With the plug out, you can also smell the spark plug hole. There should be a fuel smell. If not, suspect the fuel pump relay.

There are two areas that are likely, the first is fuel flow. There is a strainer in the fuel tank that plugs up, sometimes. You have changed your filter, correct?
The 2nd area is ignition overheat, the control module, in your distributer can react to too much heat, and cooling makes it work again. The test for this condition is more difficult, as you need to artifically cool the area to test.... Perhaps pull a plug wire and see if you have spark, during the self shut off condition.... If you do have spark, the entire area is eliminated....

Sounds more like vapor lock. Right after it dies remove the gas cap. Does it **** in air? Will the car keep running with the gas cap loose? Some cars have the vent built into the cap, so try a new one first. If it is not a vented cap, the vent will be on top of the gas tank and you have to pull the tank loose to fix, same way to replace fuel pump if it is overheating. The easiest and cheapest things to start with are the cap and then the fuel filter. Gas tank strap bolts are usually rusted on and a pain to remove.

If you have any rubber fuel lines in the fuel system, I would replace them. Over a period of time the insides of the hoses swell up and stop the fuel flow to the engine.

Turn on the key and listen by the fuel tank for the fuel pump to hum. A common problem is low fuel pressure. It will build pressure when the key is turned, use that fuel, and then the pressure drops. Kind of like when you're using a squirt gun that's getting empty.

I would definitely consider the fuel pump. I had long turnover times before starting for years, but even worse was in hot weather it would just stall while driving. Sometimes it would only idle, but not run if you pressed the gas very far. Park it for 20-30 minutes and it would run again without another problem for weeks. Dealers and mechanics kept replacing other things like ignition coils and distributors. After a conversation where someone said they had the same problem, but only when they had less than half a tank of fuel, I knew it was the pump. I replaced it myself and all problems went away.
The fuel leaks back down to the tank and air gets in the lines. Then the pump is slow to build pressure up again. If you turn the key on, but not start, wait 45 seconds, off, on again but not start, wait again, now start it will take a little less time to start, less battery drain, until you fix the problem.
You may not have the heat problem in Canada. But here in Georgia it gets hot enough that if the fuel tank is low and the pump has this problem, it will overheat and shut down till it cools. A full tank helps it keep the pressure up and serves to cool the pump.

If you have good fuel pressure, then i'ld lean towards the Ignition Control Module (ICM) it's around $40.00 at Auto Zone. They work when there still cold and when they heat up, they start to fail till they cool down again and eventually they fail totally. Auto Zone will have the step by step instruction to getting the job done. The ICM is under the rotor in the distributor, and the wires may also be corroded or broken. Inspect for any damages to the wire harness in the distributor before installing the new ICM. Good luck and hope this helps.
