Been having all sorts of problems, it started off with the check engine light coming on along with the reduced power warning. I ran diagnosis and at that time it showed 6 check engine lights. My initial thought was the computer, ao I changed that and it went down to 3 lights. I cleaned up any grounds I could and after that went down to 1 light which was the crankshaft position sensor. So i tore the intake off and replaced that, it started and ran fine for a out a day. Next time I went to start it and it was doing it again. I had a friends dad use his GM scan tool and check it out, it came back as fuel pressure sensor. Changed that and it ran for about a day again. Ran diagnosis and it said camshaft position sensor. I replaced that and once again it ran for about a day. Any ideas what else it could be? My thoughts are something electrical
