Hmmm...

Several months ago, an ECU failure (1990 Syncro westie; 175k miles) was
proceeded by several "drop-outs" where the tach would fall to zero, and all
engine output would cease.

(description of adrenaline rush and misc. excitement omitted)

Most (except for the final) dropouts could be corrected by jiggling the
ignition switch, if the dropout did not pass spontaneously.

The final drop-out was followed directly by a tow, and somewhat later by a
new ECU (which I located for about $400, core included, since my toasted ECU
was just that; toasted).

Now, despite 18 months, and only about 1500 miles, I am experiencing
drop-outs (well...only 3-4 so far) again.  Yikes!  If I had any ECU warranty
measured in time (instead of injector pulses...) it must be expired.  Any
thoughts as to the source of ECU dropouts (as symptomed by tach falling to
nothing, and engine output stoping) that comes to mind?

Thanks in advance for your assistance....
