You might need new spark plugs. They are supposed to be guaged 0.005 of an inch. It's also possible that you might need new plug wires, a starter, an alternator as well as a new coil(though I doubt that.)
.0005 inch gap. I don't think so. More likely .060 inch gap.
Your fuel pump may be on it way out possibly caused by bad fuel filter
My 1991 SSE displayed the same problem, it was a sticking idle air control valve. Carefully remove and clean your IAC with a spay can of carb cleaner, reinstall and see if it cures the problem. Agree with second poster that 0.005 plug gap is absolutely NOT correct. Plug gap should be 0.060 also a starter, and alternator would have nothing to do with an intermittent stalling problem.
You might also suspect the fuel pressure regulator (FPR). classic FPR symptoms are stalls at parking lot speed and a stops - will start good after setting overnight but longer crank time when warm. Pull the vacuum line off the FPR and if you see or small gas your FPR needs replaced.
There is most likely something in the gas tank. When the car starts the fuel pump starts sucking in fuel and when the trash gets to it the gas will not be able to flow through the clogged pump so the car stalls. When it stalls the fuel pump stops suction and the trash comes out allowing it to start again.
Probably an alternator.
See the answer to 2000 Bonneville Neutral Safety Switch Location. Had the same problem and that was my fix. You can install a separate Start Button in the Starter circuit to start the car also.
It sounds like your alternator is no longer recharging your battery. You probably need a new alternator.

my suburban wont start
Have a similar problem with my forester 1999.

The injectors may need cleaned. There may also be a problem with the carburetor not ejecting enough gas to the engine.
Your hot dog truck may be shutting down because it is overheating. This is usually an indicator that there is a problem with your radiator.
the idle jet in the carb is blocked and needs to be cleaned out and reset
It could be your torque converter stays locked up and it would act like a standard shift car would if you were coming to a stop without pushing in the clutch pedal.
Possibly Crankshaft Position sensor
Idle Air Control Valve.
IF its doing this only when it warms up, it might be a bad coil - is it getting gas?
Check your cam shaft sensor or your crank sensor, if it starts from a cold start and stalls when it warms up that might be your problem... Took me 2 months to find that out ..
Full pump is going out, or you have water in your tank. Or you need to replace the full filer(which you can find under the back seat).
It could have something to do with your oxygen/air flow sensor
bad fuel pump, you dont have enough pressure to stay alive.
It has a vacuum leak or the IAC is faulty.
