What model year is the car?

Gimme your mailing address. I've got a full set of shop manuals for 1986 Chrysler cars.
My sister fired the bro-in-law a few years ago and he sold the 2.2 turbo buggy. I have no need for these things now.
That car has a power module under the hood that does funky things when it goes bad. A more likely culprit would be the vacuum system. If that big multi-port vacuum tube is still there it can be decaying and leaking at higher temps.
Also, replace the rubber fuel lines between the firewall and engine. Those get brittle with age and turbo heat. If they fail under high EFI pressures the fuel will spill on the exhaust manifold and torch the car.

The symptoms sound like the waste gate is opening and not letting the turbo spool up. Check the linkages on the side of the turbo.

A 2.2 with no boost should still run fine but won't be nearly as quick (obviously).
If the vacuum signal to the WG is gone not only will it kill power but it will also give a bad signal to the MAP. That can cause power loss without a check engine light.

I'm going to start with the basics Fuel Pressure, Spark etc. but is there a common problem to hone in on?
thanks in advance.
As someone with a little practice working on 2.2's I can tell you that the majority of the time you are looking at a cam or distributor timing issue.
Pull out a service manual and check both. Plugged cat is possible but eliminate the cam and distributor timing first.

I will check but I think the cam timing is on. The car starts and idles spot on smooth. Runs like a top until it warms up and hits about 3k rpms. I checked all the vacuum hose and all look good. I still haven't driven it. I spent the last two days chasing a myriad of Brake Problems. The ignition system looks great but could it be the pickup in the distributor? It seems to have a dual pickup with one slightly off of the other so I figured that the second pickup was for retarding the ignition? If I disconnect either one at idle the car dies instantly so it seems to be working but still? Thanks again for the help.

Pickup will tend to set a code or just plain fail when it gets hot.
Chrysler actually combined a crank and cam sensor in the distributor, hence the two sensors.

When my pickup plate had issues, the car would just totally cut out without warning. I'd suspect the vacuum lines. My brother's car ran great, but when it went into boost it just fell on it's face without a code. Vacuum lines were leaking on boost and the computer didn't know what to do.

These cars are notorious for vacuum issues. One thing you must remember is that vacuum leaks will NOT throw engine codes. All of the sensors work regardless of vacuum leaks. The computer reads the sensors and responds to what it things is correct information.
Only a failure in the sensors will register as a code.
Since you are not getting any codes the computer thinks it's doing the right thing. That means everything electrical is probably working correctly.
If the hall effect sensor in the distributor goes bad the computer will not know that the engine is turning over. That is the one sensor that will fail without tossing codes.
BTW... the manuals are in the mail.

Not true! A leak in the baro line will cause all sorts of codes to set.
The vacuum line setup is rather simple once it is broken down, the map line is the most important. Everything else can be pretty much left off the car aside from the line to the fuel regulator.
The 10 second Relaint only has two vacuum lines.

Yes and no..
There are two sensors in the pickup.

Thank you for the help. Work has been in the way of me trying to fix it but I am staying out of work tomorrow. I will double check the vaccum lines and let you know how it goes

Fuel pump getting hot?
As stated above, get a fuel pressure gauge on that thing and tell us what it says.
