2006 Buick LaCrosse, V6, 12v, 3.8L, OHV.
While driving, at any speed, on the highway, or taking corners...the engine simply shuts off. No check engine light, no error code stored. It does display the engine light (NOT the check engine light...it's an outline of the engine), the traction control light, and the engine decreased power light (same as the engine outline light, but with a downward facing arrow). No sounds, not chiming...nothing. It simply shuts off. We coast to the side of the road if possible. Put the transmission into park and wait, never more than 2 minutes, and after trying to start it again a few times, it starts right back up and we are on our way for either 3 more minutes or up to 30 more minutes. The only thing to note is that when we try to start it back up after this happens, but before it will restart, the engine does...nothing. No starter, no clicking, no sounds, nothing. The car has 100% power. Radio, AC, windows, seats....all of it. Last thing. When the engine dies, there is no warning. It doesn't sputter to death, no lights come on prior...it's like driving your car and simply turning it off. However, the first start once it will start back up, can be, but isn't always, a hard start.
Thanks for any and all responses in advance. You want a new computer, or your PC fixed, I'm your guy. Got a problem with your car...fuck if I know.
