Check Engine Light

My check engine comes on and then goes off and back on again. Sometimes for long periods (4-5 Minutes) and sometimes for a few seconds. The oil pressure is good, the engine temp seems to be fine, the engine idles fine. Today I drove 20 miles on the city streets with this alarm going on and off for an hour.

Any Ideas?
