Help...93 s10 4.3 stopped while driving cranks but headlights not working. No run
 

Hello all. Brand new member here. Have 93 s10 with 4.3 tbi. Has been running terrific after installing new 4.3 with lower miles. Last night while driving down the road it just quit. Will crank great (very new battery) but is something electrical as headlamps, parking lights, dome light wipers and emergency flasher do not work. Brake lights and turn signals do work properly. Have checked grounds as i thought this would be the issue but no luck there.
Does anyone have any knowledge.with this sort.of.issue? Any help would be greatly.appreciated. Thanks!

It might be a fusible link gone bad. That or somewhere the system has corrosion or a loose or bad ground of some sort.
