My check engine light plus a Starlite message appears

When driving normally, suddenly the dashboard turns off, being the padlock simbol and the Check engine the only things that remain on. And still, they won't even disappear when turning the vehicle off. What is more, when trying to start the engine again, I usually need to wait between 15-60 minutes and the dashboard failure keeps appearing. I wanted to know if someone had this inconvenient and would like to share a solution. Thank you.

Had a bad jump start that fried a few things a few months ago. Replaced battery and alternator, so those are both new, and replaced the 100 amp mega fuse and A/C relays. The truck started and ran for several weeks, but then one day turned the key and it did absolutely nothing...also, absolutely NO lights on the dash display except for the check engine light. Had a friend test with scanner and it can't link with computer. Got a new programmed PCM, installed it, and same problem. I think it's a relay, but no idea which one.
Also, we've noticed that now the brand new battery goes dead quickly, like, in about 3 weeks. I just think that's awfully quick for a new battery to go totally dead. It's as if something is stuck ON and draining it. Any help would be greatly appreciated!

Después de un rato de manejarlo pierde fuerza le aceleras y no responde y petardea y lo raro q no se le prende el aviso de check engine
Después de un rato de falla se le quita y luego vuelve y así mientras está en funcionamiento

Did an update two times in a week through wifi and it completed. However, after updating every once in a while after my tuck sits at work for 12 hours, I'll get a message when I crank it up saying "Power Steering disabled" "drive with care" I don't know what it could be. Took it to dealership to check for codes because 1 time the check engine light came on. They said it was in the history and it could be something electrical. Im lost...

Engine will not turn over and Engine locked light is on

Mechanic changed oil in my truck and afterwards an engine light was triggered that said 200amp blown alternator fuse. Mechanic tried to order and it is on back order with unknown eta. So now what can I do?

Communication errors, U0073, U0101, P0700 plus three other codes. All the dash warning lights go on, once the vehicle gets warmer, shut it off and turn it back on, only service engine light is on, won't shift. Clear/erase the codes, no service engine light on, shifts fine. Put in new battery. The ABS fuse was replaced earlier
