Maybe someone can help with where to start with this. 99 tahoe approx 110k miles dies only when over 90+ outside but will restart immediately and drive for a mile or so then die again. It does have new fuel pump in last 10k miles but it's probably in need of basic tuneup plugs, wires... Anything else I should be looking at? Also, CEL is occasionally on for misfire cylinder 6 (I think, cant remember the code). I will check and see if it's throwing any other codes. Thanks
