There’s a speed sensor in the transmission for the speedometer and then a second speed sensor in the speedometer to tell the “PCM” computer how fast your going. From what I've seen its usually the speedometer itself that fails.

If the speedometer starts working again, even for a short time the speedometer itself is defective.
