Cruise control problem

[58caddy]

I have a 2005 Tahoe, 5.3 V8. It runs and drives fine normally except when I use cruise control. Cruz is fine one semi flat roads, but when I go downhill, it feels like it’s going to stall, almost like itIng itself, it feels like it’s misfiring. Any solutions or suggestions?

What does it mean that it's "itIng" itself?

I meant it’s like it’s stalling it’s self, I hate autocorrect

Have you checked for vacuum leaks into the intake manifold?
