If your loosimg all power it has to be at the source. If your loosing some power it can be be anywhere.
Are you or are you not loosing all power?
As you ignition can be dead along with a several other circuits and you still have power to some circuits
Do you know how to use a meter?
Do you know how to verify wires are good?
Do you know how to verify fuses are working properly besides looking at them?
When everything is dead does the dome light, stop lights and horn still work?
If you tell me or anything else it's stated in the opening Op again. I am done even trying to help you in this thread or matter.
Because people are trying to help you fix your issue.
Lots of times the simple things are overlooked and dismissed when they are actually the cause of the issue.
This is why folks are having you double check these things.
