The "Advanced Tech" forum is not very active, and it's not for routine engine problems. As a result, there is a warning "sticked" at the top of the forum indicating "DO NOT POST HERE", and another indicating "what this forum is for".

This is not an advanced tech problem, so it's being moved to "LT1 Bsed Engine Tech".

To get help, you need to provide additional basic info about your car including trans and any major mods.

 

Common problem that causes shutdown when the engine warms up is heat soak of the ICM.

Have you scanned it for codes?

When you go to start it and it cranks slowly, what does the dash volt meter indicate, in volts?
