Mazda made a real piece of work when the did the 626's and Miatas. I have these cars in all the time for electrical issues.
Is this an aftermarket alarm system? Or is it OEM factory?
What size engine is it. I believe it has 2 different engines that went into it in the US.
The first thing I would check is for a short or interference in the radio signal from where the receiver is.
Simply taknig to an alarm shop isn't going to do anything unless you pay them. If you can find an automotive electrical specialist in town, that would be the place to go. Tell them, you need to either have the alarm system removed or that you need to figure out why the alarm system is doing this.
Theres a tool I use at work thats made by snap on called a "Remote frequency diagnostics meter". You look for "parasitic" signal that shouldn't be there. Which can hinder the cars ability to run. When the car has been broken into or in some cases if your alarm system has "Dead Mode", the car will not start. It sounds like a you have a problem with the way the alarm system is interacting with the ignition system or the computer. I would seriously take it to someone who knows this stuff in and out, or you will get no answers.
I had a buddy that had one of these, and had 5 different mechanics look at it, same problem as you. He finally found this ASE master mechanic that ran an A/C and electrical shop. Fixed it in like an hour haha.
