Stalls when warm

My aurora is stalling when it is warmed up. The SES light is on when it is stalling. I have to step on the gas to keep it running when slowing down and stopping. Sometimes it runs fine when warm and the SES light turns off. I notice the problem more when it is really cold outside(below 10 farienheit).

I had the SES codes checked at autozone and i got...
P101 Mass air flow
P305 #5 misfire
P155 O2 sensor bank 2
P139 O2sensor bank 1

I already changed the plugs but that didn't help.

Any ideas on what to tackle next. The guy at autozone said that one issue could be causing all the codes to come up.

Have you had any work done on it recently? I know that when I forgot to pluc an electrical connection on top of the EGR valve the P101 error came up for me. So I'd check for any loose/unplugged electrical connections first. You also might have a bad FPR(fuel pressure reglator), or spark plugs and wires. I'd go with easy things first tho.
