no spark at distributor

I purchased a new mallory v8 billet dist. w/tach. drive #7564501 for my 69 chev. corvette. 350cu. eng. th400 auto trans. The dist. was installed by a Corvette dealer in Houston and was working fine when I took possession of the car. I have only started the car 4-5 times since the dist. was installed. Recently the engine started to die at idle and would not start again unless I waited a minute or two. After a few times of doing this the car would not start at all. The carb. is getting fuel. The battery is fully charged. The dist. is getting full voltage when cranking. I confirmed this by running a jumper cable directly from the battery to the battery term. on the dist.  I am not getting spark at the spark plug or the distributor. Maybe faulty ignition module?? Any ideas??
