I just went trough the same exact issues & symptoms. The DIS is Distributorless Ignition System. I replaced the ICM (ign control mod) for $130 and still had the problem. Next I bought a cam position sensor from autozone for $38 and that did it. The cam position sensor is right under the blower snout just to the pass side. I'd try just the cam sensor before dropping $130 on the ICM.
I'm willing to bet that'll solve your problem.
