I have a V6 3.8 cutlass ciera. When the engine gets warm the car stalls. After it stalls the first time it will start but real soon after it stalls again. After 2 or 3 times of this happening it doesn't start again. It had an overheating problem which I changed water pump, thermostat and had the Rad rodded and cleaned out. Does not show overheating anymore. I have also replaced fuel pump, fuel filter, air filter, oxygen sensor. My muffler is corroded and has a rough idle and start. Any ideas what it could be?

Next time it stalls don't wait for nothing try to catch it if its fuel or spark problem-Do below

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
