Hey ya i had the same problem you had, the dis module would keep shutting down then coming back and it was just getting annoying. Just go to your local junk yard and pick one up, mine was 50$ no big deal, grease it up with the dielectric grease and its good to go. you can purchuse a new one for about 350$$ (canadian) thats what i got quoted, but i talked to one of my friends who is a ford senior mechanic and he told me not to bother with the new one because the failure rate of the dis modules is very low, ( i gues you were just luck

)
