If you tach is diving for zero and the car is still stumbling, then backfiring, it's got
nothing to do with the above...  You've got a problem with your ignition cutting out.  I
remember this exact problem on one of my cars, but damn it, I can't remember what ended
up being wrong with it...   I guess the first thing I would do is check all your
electrical connections at the distributor, coil, and ignition module.  Also check your
grounds.  If you've got another coil or ignition module lying around, try swapping them
in and see if that's your problem...  If I remember what was wrong when I had the same
problem, I'll let you know...

HTH,

Mark.
