its fine till it gets to running temp then runs for a while then shuts off and wont turn on till it coolsi changed the spark plugs fuel pump but they all worked fine so i dont know what the problem can be my maf was really corroded also but i just cleaned it all up and its perfect now, could the maf cause this problem

it could cause your problem but just to let you know ive seen alot of these cars with a coolant temp sensor problem when the CTS dosn't know the engine temp it can't adjust the fuel table accordingly and it stalls
