Silverado Issues

[Gary Kitelinger]

Ok, I have a 2003 Chevy silverado 1500 HD.  After the truck runs seemingly fine for 10 minutes it begins to sputter and backfire.  It will actually die.  I have replaced all the fuel lines, throttle body, pressure regulator, fuel filter, fuel pump, cat converters and the same issue continues to happen.  I really like the truck but I am at wits end trying to resolve the issue.  No one I have taken it to can seem to fix the issue.  I can say that for some reason after those 10 minutes when I make a turn the issue gets worse.

No stored codes?

The trucks history could be a factor. How well was it maintained? Was the motor replaced? Could be a pinched or frayed wire. It seems related to a warmed up engine. 

Someone will be more help.
