Hi there, I'm new to this so bear with me. I have a 97 TJ, 2.5.
My problem is that once in a while, the oil pressure and the idle
drop, the buzzer come on and a light comes on in the dash.
Oil pressure is normally 45 psi, and the little beast runs good.
Any takers on this problem?

Of course, I'm sure you checked your oil level. But, when is it occuring? Are you driving down the street, or is it at a steep incline or decline when off roading? If #2 it could be that the oil sloshes away from the pickup tube and that will account for the drop in pressure and decrease in RPM could be caused by oil flowing into cylinders and around rotating assembly during incline. Or could be caused by a faulty ECM, if RPM drops, oil pump is driven under load from engine-> your drop in oil pressure.

my 4 squirrels were doing that a while back. eventually, my alternator went out on my way to AZ. hasn't happened since. not sure if that was the cause or not, but like i said, since i replaced the alt(the only thing i've changed recently), the little guys stopped slowing down like they did.
