The problem with wireless is the same problem with anything else that uses radio signals, that is RFI (Radio Frequency Interference). There are many sources of RFI, from pagers (which seem to be able to wipe out any radio signal within 10km) to electrical transmission lines to portable phones and microphones, even the traffic signal box, and the car your beside. The transmitter on a wireless bicycle computer uses an incredibly tiny signal, for a couple of reasons, one it has a limited power source and two it's limited to the restrictions within the unlicensed radio bands. It doesn't take much to disrupt the signal, and then there is a problem, you either lose a few ticks, or you gain a whole bunch of false ticks. If there is too much interference the unit has to give up until it can re-establish the connection. If it gives up, some of them may do a complete reset to zero, others will estimate the missing data. Seems reading down further that the Cateye will reset to zero.
