I had seen this happen several times in the mid-90's, in NY, Vermont and once driving in Maine towards NH, what was common each time was:

No clouds,clear sky
time of year was between late spring to early fall
it always happened around sunset

the last is odd, because when the sun starts to go down and the first stars appear, those are usually the planets of our solar system that appear first

the stars I saw were in the sky a good 5-10 mins before blinking out, the one that I saw while driving (it was in the direction that I was driving and it was the only one out was there and constant for about 5 mins, then blinked out, only to reappear secs. later, stayed for about 20 more secs., then went out, then on for 2 secs, then out completely

this one and another I had saw in upstate NY a couple of yrs earlier both had an orange hue
it was because of the that earlier orangish one that went out that I kept an eye one that other one while driving, as I had a feeling it would blink out

that was the last time I saw that type of phenomena
