I have a ‘99 3.8 5 speed V6 that keeps shutting off on me. The “Check Gages” light will come on and off but mostly stays on and my oil pressure will be bouncy usually between 55 and 75. It will randomly shut down while driving or idling and won’t start back up unless you push start it and then after that it will start up normal again. I’ve gotten my alternator tested, I’ve changed my fuel filter, I’ve done an oil change, I know I have enough fuel and engine oil and I can’t figure out why it’s shutting off. She runs fine while she’s on.
