Sudden Lean and missfire

Hello,

I have a 13 F150 5.0, while driving, vehicle started missfiring with loss of power.
Ran codes at home and got p0300, po302-304, and p2195 too Lean bank 1s1

We replaced plugs at 100,00, it's at 105,000. No other issues at all.

Help please!!

Does fuse 27 in the battery junction box look melted and/or burned?

Sure seems like a lot of 2013 5.0’s are having this mystery issue. I try not to believe in predetermined obsolete-ism conspiracy theories but I’m starting to feel this way with Ford.
