This is a common experience when the timing cap inside the gauge is
leaking but not quite enough to fail hard and just blink all the
time.  Both the key on, wait, key off part and the sensitivity to
temperature and especially to humidity.  Given the symptoms it's not
likely to be anything else.  Van Cafe has the gauges for
tach-equipped vans and in a pinch I can fix them if you can't, or
can't get it done nearby.
