Remove and dismantle ur distributor. U have to take the "C" clip off of the the thing that mates up to ur camshaft. Is there oil inside? I think that the main bearing allows oil inside, goobering up the pickups inside. Doust them with brake cleaner and put it back together. This shud fix it temporarily. I have that same problem. I need to buy a new one but im poor. Lemme now if that works. I cleaned mine about a month ago and its starting to do it again. Its a band aid but I wanna know if it works for u. If so, that means it not something else.
