Engine shuts off 09 Tahoe

[2799gret]

I have a 2009 Chevy Tahoe. The engine has been shutting off once a week when I slow down. Electrical still works. I can crank the car right back up after. No check engine light comes on. When it happens the steering wheel locks up and the car decelerates to a stop.
I don’t know where to start.

Start by not driving it on public roads with other traffic.

Thank you for this comment. This is not our daily driver. We drive this on our farm to haul supplies. So…not on public roads.

you're going to need to basis tools like obd scanner with data to really do anything besides guess. you need to check the basics like does it have fuel pressure when it dies, is it running badly.

but more story might help if they guys have seen this before. what are you doing when it happens. how does it run, passed maintenance and mileage. could be as simple as fouled our plugs, to a throttle body that needs cleaned. hard to say without knowing more.

Does the steering wheel really lock up, as if the key is removed? Or does steering get stiff, as in no power steering?

Sometimes the cats cause this before throwing a code.

MY2009 does not have a mechanical steering lock as far as I know.
