I have a 2006 Trailblazer LT and recently whenever I stop at a stop sign/red light the vehicle starts to shake a little bit and wants to die on me. The only way I can keep it going is to step on the gas. What could be wrong with it? Please help.

Possibly a fuel pump issue or a torque converter stator issue? These are just suggestions, not a diagnosis. It is difficult to diagnose an issue like this without an inspection. I encourage you to take the vehicle in to be inspected by a certified technician. They will be able to offer additional information after a physical inspection of the vehicle.
