You shouldn't be losing counts (which is why we love using them).
However, if you are there are two likely causes.
1) Mechanical slip. Somehow the encoder is slipping, easy to fix w/ better design.
2) Voltage brownout causing the supply voltage to the encoders to drop out. We use a regulated supply for all of our encoders for this reason.
