You haven't described what the problem is, so you'll need to do that. Also mention if you've done any testing with a meter.

Disgnosis is need to resolve this issue, not hanging on parts over and over again. My guess would be a corroded or loose wire, or a short, but testing is need in order to determine the actual issue. It sounds like you don't DIY, so you need to find a shop that knows what they're doing. An auto-electric shop would be best for this type of problem, but I don't know what they're called in Canada.

I would be looking at things on the ground side of the system. The only time I have ever had an alternator go bad that many times, the engine ground was none existent. (completes the circuit to the alternator). but with a car like this, the ECU would show other issues with a bad ground.

I also don't know if you have a parasitic draw issue or what you are describing, but the fuse box sometimes "melts" to allow bad things to happen.

I recommend a good electrical shop as well.
