external lights often run off relays in the fuseblock, in the engine compartment- its a 2nd fusebox for exterior and/or engine electrical systems

no, only when your AC or you defrosters are on

It appears you are willing to throw a few parts at it, and see. Here is one to try. There are 2 engine coolant temperature switches that screw into the block. One controls the fan that cools the radiator in the front. The other is hooked to the computer and tells it what your engine temperature is. Specifically, it tells if the engine is cold or hot. When this sensor fails, it will tell the computer that is engine is cold when it is not, and then the computer will make it so the engine will not start. Sometimes these two sensors are even the same part number. Try replacing that (computer) temperature sensor, it should be cheap. God bless your efforts.

This is a common symptom (if not the most common symptom) of a failing starter. It will crank when cold and will not crank when engine gets hot. This is a failing condition and eventually won't crank when it's cold either. It's also possible but not nearly as likely that the timing of the motor is too far advanced. When the motor warms up, the timing advances further to a point where the motor is too difficult to crank.

Check battery connections, make sure they clean and tight. Often there is enough connection for a light but not good enough to pull high amp starter.

OK sounds like head gasket or vapor lock hope its vapor lock need to bleed off all air in system turn on heat while radiator cap is off feel top hose make sure both hoses are warm with everything changed is fans even coming on an if not turn on ac an see if fans come on or not If you need further help, I’m available over the phone at https://www.6ya.com/expert/robert_c7b5aba9012a13b2

Sounds like it might be related to fuel pressure sensor which can give the same problems as a clogged filter. Since you changed filter, then it probably is fuel pressure issue, fuel pumps have produced these kind of symptoms as well. Check fuel pressure at fuel rail after it stalls and when you try to restart, if no fuel comes out shrader valve, then fuel pressure sensor may be the issue if not the fuel pump itself. Had similar problem on Volvo recently, and most fuel injector cars are the same. If there is no missing or bucking before stalling, it is usually a fuel issue. Is it consistent issue, or random?

You don't, usually if the brushes are worn to the point that they need replacement the slip rings that they are in contact with are worn through too, you are better to just replace the alternator.
