The only thing that will surely kill Thyme up here is if the soil is too dry for too long. In the winter my potted thyme comes indoors and will eventually go dormant and die back, but if the soil isn't kept slightly moist all winter, ir won't return in the spring. The plants I have in the ground don't need much attention since lack of moisture isn't an issue here.
It will get long and straggly with small leaves if there isn't enough light, but yours is getting plenty of sunshine, so maybe it needs some fertilizer. I fertilize in the spring when new growth appears with liquid fish/seaweed and then a light dusting of a granular organic fertilizer on top of the soil.
