Welcome to TW...Hope you get it figured out!

 

I had a similar situation with an '03 4runner. Turns out, the ECU had been compensating for a dirty throttle body over the years. Once it reset, it wouldn't stay running. I cleaned out the throttle body with a rag and brake cleaner and everything was fine. It might be worth checking.

I would check the wiring for shorts as well.
