ENGINE DIES

2005 Chevrolet Uplander • 92,000 miles

Almost daily, the engine on my wife's 05 Chevy Uplander just dies. It fires right back up when you try, but it dies randomly, there aren't any situations where it dies more often than others. Any suggestions?

Check the fuel pressure if its within specs with a fuel pressure tester-start here

Have codes read by local auto store for free. See if anything pops. You didn't mention if it dies at idle or while driving. Crank sensors are notorious for driving stalls. Cam sensors too.

It stalls while I'm driving.
They'll be able to pull codes even if the check engine light doesn't come on?

The CEL has to come on with key at run position to run a scan

Light can go on and off again and leave code.

Fuel pressure is good. The check engine light finally came on and showed an error with the MAF. I pulled it off and it is clean and looks good. What else could cause the MAF code to pop up? It seems like the colder it gets, the more it stalls. Lately it has been stalling more when I and making left turns.
