1999 Tahoe Lt 5.7 Stalling Problem

[Trailduster]

1999 Chevy Tahoe 5.7 LT with 222k miles will stall at random times....sometimes after you first start it...but is getting worse and will stall while driving down the road. When it stalls there is no check engine light coming on and the radio clock resets. I am thinking the ignition switch after I saw another post on here. Also my Daytime running lights are not working...they used to work but have been out for probably 3 years before the stalling problem...the light on the dash for them does not come on. Also how do I know if I have pass-lock so I can order the correct ignition switch? Any adivce would be great...the tahoe is great otherwise. Thanks Mike

It's not the ignition switch if the clock resets. Check battery connections.

is the truck cranking well after it stalls? if not I would suspect the Alternator has kicked the bucket.
