2010 Tundra will not stay running

My 2010 Toyota Tundra with the 5.7 flex fuel will start up and then shut right back off when hot or it is warm outside. In the mornings it runs just fine. If i can get the rpm up and able to hold it for couple of minutes then it will run fine. I put a new battery in, two new camshaft position sensor, o2 sensor. I had a after marker remote starter in there but removed it and hook every thing back up. It will stay running with starting fluid as long if you keep spraying it. The fuel pump is is pumping about 45 psi. Tried a different key. And the only code on there is p0420 code. I did had a squirrel to get in the engine bay and chew up some wires couple of years ago. Any advice will be greatly appreciated.

Thanks

OP here are threads with that code so you can review. Is probably a bad 02 sensor. You may have other issues however and rodent damage to wiring is certainly a possibility.
