If it is repeatedly on the same place, it's something with your layout.
It it occurs randomly at different places, then you are loosing steps. This can have quite a few causes:
most common causes are too high accelerations or speeds for your motors.
but dents or dirt on your guiding (rail) can be a cause
The powersupply malfunctioning, a heated stepperdriver, bad contacts, a break in the cable etc etc..
You have to check it all...

I get similar things happening. I've opted to upgrade to a closed loop system. I had a fire in my laser anyway so decided to rebuild the x axis with closed loop. At least you can eliminate a few things then.
