Cutout throwing 02 codes?

Does anyone have DTC issues with running a cutout? I get about 15 miles in with the cutout wide open, then the car starts running like crap. Popping, missing, like all the plugs are fouled. Sometimes it throws 02 codes, sometimes it doesn't. When this happens, I just have to clear the codes if thrown, and disconnect the battery for a minute, and presto, good as new...for another 15 miles. The cutout is a good two feet from the 02 sensors, so it shouldn't matter. Of course, this is a 98 ECM, so maybe I just need to do the repin....any suggestions other than that?
