Start at the rear of the engine and be sure you have a good connection
at the pressure switch. It is located at the bottom of the crank pulley
and can be reached from up top, but it's a PITA. If the connector comes
off the switch so that you have an "open" circuit, then you get the
solid buzzer and light. The intermittant nature of your problem suggests
a loose connection. The most likely place is the connector at the
switch. Then work forward from there.  I have had to deal wityh this
same kind of problem several times and though the causes were different
each time, it always came down to the connector or the switch itself.
Also don't forget the switch on the right side of the engine between the
pushrod housings.

Good Luck.
