The only reason for this is that the 6502 is fetching a opcode every cycle
ie. the 6502 does nothing or reads the same instruction all the time due to
a damaged ROM or whatever has to do with the databus.
This is an ideal problem to be solved using a debugger:

Hmmm, the GIF is missing :( If you need it, mail at ABP. Otherwise I (hope
to) put on my site this evening.
