try checking your fuel tank for sediment it may be clogging the fuel pump and when it dies it falls away then when you start up again it gets sucked up

SOURCE: 1992 buick lesabre starts fine.

You check the coils with a ohm meter. They should 6-8 thousand ohms at the spark plug connections. One lead to one spark plug connection and the other lead to the other . It's not likely a coil for stalling. If coil , Your car can still run on four cylinders. It can be a ignition module. It fails when it gets extremely hot. The module is located under the coils.

It's got all the symptoms of a leak in the fuel line. You may want to start backward at the tank and work your way all the way to the carb to find it but it would be surprising if it was something else. All the best.

first..you need to find out why it wont start after it dies... ck spark? ck fuel pressure? ck injector pulse?ck for 5volt reference voltage at throttle position sensor?old school hasnt changed much, you still need fuel, fire, and compression, we KNOW compression is OK, so you need to find out what you are losing. spark or fuel? drive it with fuel pressre gauge, should be 40-45psi. ASD relay is a big player.
