Gmc Electrical Problem! Help!!

[NELSON]

otay, trucks 95 yukon. driving down the road the truck will just turn off. EVERYTHING electrical goes off. moments later it will crank back up and everything will be fine, but when it dies it wont do shit! so i get in it yesterday to go and it cranks up i put in gear get about 10 ft and it turns off. so its obviously not the battery and the alternator is charging. now it is just sitting and the head lights wont even come on. they should come on without the key even being in the ignition. the hazard work ,but barely and the relay is makeing some funky noise. when you turn the key over to crank the rpm guage GUage goes all the way up. the key and tumbler is jacked up and some time hard to turn but this shouldnt effect the headlights because u can turn them on without the key even in. does everything electrical run through the ignition switch? very weird, someone help me out!!

Check the + cable that runs to the starter. My Tahoe and a friends 94 PU did the same thing. Not sure if they corroded internally or were breaking off internally or just getting hot but after fixing his my Tahoe started doing it and replacing the + cable took care of it.
