At the moment, it's kind of hard to narrow down the possible problem. Just
off the top of my head, I can think of:

* bad swtich on thermostat
* loose wire on back of thermostat
* faulty contactor on condensing unit
* bad capacitor to condensing fan
* bad capacitor to furnace fan
* bad contactor on furnace fan relay
* bad contactor on back of thermostat
* low output voltage on transformer in furnace
* dirty connections on outdoor disconnect
* weak circuit breaker to furnace
* weak circuit breaker to condensing unit
* bad starting components on compressor
* Loose wire on compressor
* Loose wire (one of the fifty or so) in furnace
* Loose wire on contactor outdoors
* Compressor cycling off by way of thermal overload
* and about four others I'll think of when I hit send
*
*
*
*

But those were just the ones which came to mind off the top of my head.
Central AC is a rather complicated device, and needs a techie every year to
clean, check, oil, and so on. Please let us know what the techie finds. Live
long and prosper.

Twice this summer our central air stopped running. The one time we
got it started again by just flipping the off and on switch a few
times. Last night even that didn't work so we just went to bed. It
suddenly started this morning after I played with the switch. I
don't want to call in service until I am better armed with information
(I don't want someone trying to sell me a whole new system when it
might just be a loose wire or something).

Anyone have any clue if that is a symptom of a thermostadt problem as
opposed to the ac unit itself? We have a Hunter programmable
thermostat and I changed the battery on it last night too.
