Car for my daughter continues to be a shetbox. 

Loss of power/dies this week.  Per codes, replaced 2 O2 sensors and cleaned MAF.  Same issue today. Barely gets out of the driveway.  Heavy exhaust smell.  Same codes pop back up.

Has the Cat gone bad?  

If so, what's the best route to replace.  CA legals ones are expensive as hell.  They need to be welded on?  2010 Equinox.  Only 130k miles.

Buy an 8-ball, go into Barrio Logan or Lemon Grove and find a tweaker.  Offer said tweaker the 8-ball in exchange for the cat(s) you need.  BAM!  Problem solved.

That's really weird for all those codes to be up especially after you've changed them. I did a quick search and a lot of other people were complaining of blown fuses and bad wiring to some of the sensors.

As far as the catalytic converter. There's a local smog shop that I go to all the time and he was telling me "approved cats" is a scam. He showed me in his book all the cats available and 90% of them don't exist anymore.. He got me squared away with a universal cat. Go down to https://g.co/kgs/t5WBFd

and talk to him, he'll help you out. He's an old school Vietnam vet, owns the place. You'll probably notice all the bags of ammo. He reloads and sells ammo, too.. (not to just anybody)

This was a code from just a bit ago regarding Catalyst.

Oil pressure switch was replaced just after.

Ah!  Another number related to catalytic WAS blown.  Test drive now...

 
Fuses don't usually just go bad....there is probably other stuff going on.....best to be rid of it while you can.....

 
The first place I always looked for the cause of an O2 heater circuit blown fuse was wires touching the exhaust. Sometimes they will be really close and wont actually touch/ground out till its driven and shook around.

One of the older O2 sensors was rubbing on the front driveshaft.  Went through a wire and likely blew the fuse.   Everything made sense yesterday afternoon once the whiskey started.

 
I’ve had a bad engine coolant temp sensor give me hell in my buggy. Made it hard to start  once started it was very rich  I tested it it appears to be on the cold side and stuck there so was telling the ecu to add more fuel 

in your case a bad cat or o2 sensor should not make the car barely run.
