You're going to have to provide more information.
Automatic or manual transmission?
How many miles are on the car?
What is wrong with it?
What have you done to try to fix it so far?

It’s got 150xxx miles and I’ve had a couple ppl come look at it but nothing concrete and I don’t wanna get Rid of it so I have it sitting in my Garage, I can hook the battery up and it struggles to Start but after sitting idle for a while if I give it some gas it shuts off then it take days before it starts again

Smoking turbo yay
Sounds like multiple things.
Start with a compression test, ideally with a rotary-specific compression tester. An analog one isn't the best to use, but if you want to get a rough idea on compression then it will suffice. If it reads some stupidly low numbers(anything below 90 psi), your battery is fine and you don't live a few thousand feet up, your engine is toast and you will need a rebuild. A reman is around $3k from Mazda for a 6-port(any manual and 06+auto). 04 and 05 auto engines will cost a bit more. The installation will be around $1.6k by a dealer.
If that's not the problem, the next things to check are the coils and the catalytic converter. If the coils are OEM and you don't know the history of them, it's safe to just assume they are bad and should be replaced. Take the catalytic converter off as well and look inside to see if it's clogged or damaged otherwise.
