I'd guess that some self diagnosis is in order.
When the problem occurs, and you can pull over.
Check to see if the A/C clutch is engaged. You may be able to carefully
"thump" it with a piece of wood, or whatever, and see if it engages.

Also, one of the odder problems I've seen had to do with the compressor
reed valves. seems that one was broken, worked part of the time, and
when it sort of wandered around, did not.

Is the 92 filled with the "old" Freon, or the EPA happy stuff?
