Answer:
I can run but not walk. Wherever I go, thought follows close behind.
Golden treasure I contain, Guarded by hundreds and thousands. Stored in a labyrinth where no man walks, Yet men come often to seize my gold. By smoke I am overcome and robbed, then left to build my treasure anew
I'm light as a feather, yet the strongest man can't hold me for more than 5 minutes.
My first keeps time, my second spends time, my whole tells time.
I can be short and sometimes hot. When displayed, I rarely impress.
I have two eyes in the front and a lot of eyes on my tail
