91 Suburban Nightmare

[KazuyaIB]

First of all let me state that I am lost but maybe someone can help or at least guide me in the right direction...

My suburban started dieing on me last night. The low beams and interior lights go out as well as the ECM B fuse has no current going to the fuse...

I see no connection between the lights and the ECM B fuse...
The weird thing is if i let it sit over night it works the next morning great but as soon as i turn the low beams on within a couple of minutes it dies.... Wiring issue? Wonder if anyone has had this problem before. Any help would be amazing, thx
