engine stalls after 5 minutes. runs smooth up until stall.

Sounds like a fuel concern, but could be an electrical issue also. The fuel pump is in the gas tank and will need to be dropped down to have the fuel pump replaced, also you should the fuel filter replaced if it is external mounted. I would start with the fuel filter and an a fuel induction cleaning this might help the intake and the fuel rail & injectors to work better. This would be a quicker test to the concern that you are having.

The fuel filter is located inside of the drivers rear wheelwell. If you remove that tire, you will see it and have access to the fuel pump, which is at the top of the fuel tank, which is just in front of the rear axle.
