Engine Performance problem
2002 Pontiac Trans Am 6 cyl

2002 pontiac trans-am. It runs perfect for about 5 minutes, then once it warms up to operating temp. it sputters then cuts out. i have pulled codes for,
oxegen censor low voltage bank 1 and 2, egr valve insuffecient flow, catalyst efficiency below threshold bank 1, and also an EVAP code, I replaced the oxegen censors bank 1 and 2 that are by the manifolds but not the one that is after the catalitic converter. now I cannot get it to start even when it is cold? what should I check?
