What would make my 2006 Toyota Sequoia idle rough, loose voltage, and die?
What is your question?
I've replaced the battery, the alternator, and check all the wiring I can get to for any thing grounding out. I hooked the code reader to it and no fault codes come up. When I first start it, it runs okay for about 5 minutes but only about a thousand RPMs. Then the idle gets rough, I start to lose voltage, the headlights start to dim and eventually it dies. I'm not sure what to check before I put it in the shop. Please help
What makes this problem better or worse?
If I try to drive it.

It sounds like your 2006 Toyota Sequoia could be experiencing a fuel delivery issue or a problem with the air intake system. A clogged fuel filter, a failing fuel pump, or a dirty mass airflow sensor could cause rough idling and loss of power. Additionally, check the throttle body for any buildup that could restrict airflow. Since you’ve already replaced the battery and alternator, focusing on fuel and air delivery systems would be a good next step.
