My car dies idling and running down the road with A/C on, but fine with it off.

What is your question?

The first thing to happen was my A/C shut off for an hour or 2 and started right back up, then 2 days later my car died at a stop light. Now its so bad that it did it yesterday while I was driving down the road. All of this while the A/C is on but it is just fine as long as I keep it off.
