Hi Mike --

Like Patrick says, it could be an ignition problem.  Try the plug test:
get some good gloves, run the rpms up to a stable 1500 or 2000, then
pull a plug wire (with the gloves on!).  If you've got a dead cylinder,
the rpms will not be affected when you pull the plug off.

Try it and let us know what happened!
