do you have any OBDII tools or have you had a shop look at it?

I would be wanting to see the raw OBDII data to see what the fuel and spark systems are doing. You're losing one of them, just need to find out which.

 

What about the iac? Was it taken out and cleaned? Next time it dies give the throttle some gas when you try to start it.

 

iac was replaced already

 

have you been throwing parts at it or a shop?

A shop with a DRBIII or proper advanced OBDII tools could probably have solved this without throwing parts at it. Either you're losing fuel pressure or spark. Fuel pressure is just a pressure gauge. Spark can be checked through OBDII or a timing light.

 

Is the coil new or you checked it? A coil tested may show as good but be bad as it heats up.

 

these are all new parts, that have not fixed the issue, issue has stayed the same and even got worse over time, run time before failure has been getting shorter and shorter.

 

Has this had an engine swap or any work done to it before the problem?

Clogged cat?

 

new, cats, after issue started, all parts are new after issue started.

only thing new was trans rebuild before issue.

 

you've already done the parts chasing. Just take it to a dealer so they can hook up the DRBIII and figure out what is wrong. That's why they have a $15,000 computer. A $300 diagnostic fee is cheaper than all the parts you have blindly thrown at it.
