I have replaced intake gaskets, top, and bottom. Plugs, wires, etc. The only code still present is cylinder 6 misfire. Very perplexing? Starts runs for a couple of min then dies.

Test for injector issues, including the wiring. A while back I had a sudden cylinder 3 misfire P0303. Narrowed it down to a faulty injector (stuck closed, also threw lean codes). Replaced it and problem fixed. You should have checked when you had the top intake plenum removed. It'll have to come off again if you need to access the injector :\
