    I do not think it is the fuel pump becasue the engine did restart immediately after I pulled over and turn the key to start the engine.

    Could the ecm be at fault?

Run an OBD 2 test for trouble codes, the PCM or ECM as you call it is seldom the cause, less than 2% of time I was told in a factory school I attended on electronic engine control systems, Kragen and others will run this test for free, also You say I think the fuel pump isn't the problem, not good enough, check the fuel pressure, never just quess, know for sure, do the tests.

It sound like you have an injector problem. the injectors may not be giving the engine enopuph gas to run. so the engine will stall. the fuel pump with shut down as a saftey measure.
have you injectors cleaned and checked for consitancy.

It's losing one of two things - fuel or electricity. I would check and or replace the fuel pump and fuel filter first.

Continous surging and stalling


Per your description, I would suspect a fuel pump issue. When the fuel pump is running the pump impeller heats up. On an older pump the impeller can begin to seize up and momentarily stops and starts. Some times it just stops and has to cool down for a couple of minutes, then is ok for a while.
To test this theory, when the engine stalls and stops, your mechanic can use a rubber mallet and hit the bottom of the gas tank, this will free the pump impeller and the car will start again.
Or, have him install a fuel pressure gauge and go for a drive. If the pressure begins to fluctuate and drop, you know the pump is causing the issue.
Good luck, let me know.

Stalling


Possibly faulty ignition module is the problem, stalls when engine is hot when you sit for a while it cools off and runs again until it heats up again, those are usually the symptoms of a bad ignition module and after a while it may give out all together and not run at all, usually if the module is at fault it shuts down the fuel pump so the engine don't load up with fuel, do to when engine continuously cranks over the injectors never stop squirting fuel and flood the engine do to lack of spark which is produced by the module, this could possibly be your problem.
