I suspect your idle is not increasing as it should when the compressor engages.
You have an idle air control valve on the throttle body. The PCM, engine computer, controls it. When the PCM gets a signal from the /ac clutch engaging, it will increase the idle to compensate for the load of the a/c compressor.
You may have a wiring issue to the PCM that it is not receiving the signal on a/c clutch clicking on and off.
you could try disconnectint rthe battery for 2 hours and then reconnect and drive for 10 miles for the ocmputer to relearn it's stored memory. Try that first.

I've been working on my 2001 Ford escort zx2. I
Buy a Haynes manual for $15 for starters. Remember that coolant systems also have tranny cooling functions too. They needed to install them because the trans are getting cheaper and cheaper (this ain't the old days) and keeping the fluid cool is important. I've worked on a 97-98, but they aren't that far apart despite the P-engine vs. DOHC. You might even have the ever present Check the Haynes (or Mitchell or AllData - the Ford Dealer will probably print you a page or two for free on this so you can see how things are looped) - and you can get things put back together. You didn't say auto or 5 speed, but I suggest you check out the MANY devoted forums to Escorts and Ford Focus. Your answers likely lay there as well.
Problems starting
First of all...... Why do you have a ignition interlock device on your car?? Is it a breath analizer from the courts ?? If so..... this device may be the problem..(defective part). If it's not a court issue breath analizer, then remove it and see if the concern is still present ?!! So .... when you say that the car will not start,,,,, does the engine crank over and won't start ?? or you turn the key and the engine does nothing ??? it makes a difference .... I'll need to know this before I can help you !!
