thank you for that information

the odds are when this happens the issue will be a big ground or a big power being not enough volts or a bad connection which will cause this problem

the best action to take is to make sure both battery cables are clean and tight if they are and the battery and alternator test out good when tested then you need to follow the ground battery cable and be sure it is clean and tight where it connects to the engine and the smaller grounds connected to the transmission to engine bolt studs in the area of the starter where the engine meets the transmission front bolts

if those are clean and tight and the body ground is clean and tight ( which should be one of the grounds off the negative battery cable ) then the only thing left and is very common is the ignition switch itself not sending full 12 volts to some of those circuits causing this issue and replacing the ignition switch would be the next step not the ignition lock cylinder and key but the electrical ignition switch that the ignition lock turns located on the drivers side of the steering column opposite of where the ignition lock cylinder is
