2010 GMC Yukon major electrical issue

[salyermarlin]

2010 GMC Yukon 5.3L 170,***
Whenever you start up the car and first put it in drive the radio will start making a popping noise like you’re hooking/unhooking a aux cord and just go black for a minute and then come back on. While it’s off the lights on the dash start flashing, the doors keep locking/unlocking, headlights flashing/dimming, and the car will not go over around 10-15 MPH. I’ve tried my best to figure out what’s wrong but I’m not a mechanic and I can’t take it to one cause all the ones where I live always say it’s something major and charge you thousands and keep the car for weeks and barely touch it before giving it back to you and it won’t even be fixed. So I need help so I can fix it myself. This is my wife’s car and she uses it to take our son to school everyday so I need this fixed ASAP

I forgot to mention that I have changed the 175 mega fuse and the oil pressure sensor is bad but both are very recent and this issue has been going on for months

Trouble codes? Do you have a code reader to pull engine and other internal codes?

How old is the battery and if you put a voltmeter on it in the morning, what does the voltage say?

This reads like a connection issue. Either your battery cables are corroded, your battery is bad in some way, and or your grounds are corroded and need cleaning/replacing.

Less likely but still could be is that your Body Control Module needs replacing.

Knowing the codes and voltage and is going to get us started on finding the problem.
