My tach has started cutting out at random. It works correctly then drops to zero then sometimes comes back...any ideas?

try the tach sending unit, u can pull it apart and place a piece of paper between the cover and the contacts, alot of times thats a quick temporary fix, if that doesnt work, then replace it, i think its about 60 bucks or so.

As Daniel H says;

Good work - just add paper folded - better - a slice of cork stopper from wine bottle- if you have some OX-GARD- put those on the male plug tips - mercedes is fond of using metal coating that will oxidize

can be found at any decent hardware store

good luck

I pulled apart the tach amplifier module and put a cut out circle of corrugated cardboard behind it. This provides helps force together the plug connection. It has been working great for three weeks now. Before I had an intermittant tach then it went completely dead.
