2003 Ford Taurus 3.0 L with 104000 occasional all the lights in the car will flicker (pulse) then after a few minutes everything is okay. Is this a alternator problem?

Could be, but to be sure you would have to monitor electrical system voltage using something such as lab scope. A volt meter won't be fast enough to see the change in voltage and will average the reading. There also could be something such as a heavy electrical load turning on and off causing pulsing lamps.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Sounds like a loose ground wire to me.

There is no single ground connection that effects all the lights and nothing else.

I remember in my 84 1st gen S10 that I had a 350 V8 in there was a grounding wire and nut below the dash on the drivers side by the fuse box that would always get loose and it would cause my lights to "pulse" from full power to dim back to full power and such. I would always hand tighten the nut when this would happen and it would be all good until that nut loosened up a bit and that wire wouldn't make a full connection.

Don't compare a fix for another vehicle to this one never mind the wild age difference,
