Default Pcm

So I had troubles with my 05, driving car would die, get shakey, rough idle, dies had to wait 20 minutes then it would start. Throw mass airflow code and tps codes. So I started to fix it. Cleaned throttle body checked for vacuum leaks. Worked for a few days, went back to being stupid again. So bought new throttle body and new mass airflow sensor. Did good for about a week. Throttle body is good now just mass airflow code. Then the car would start dieing on me half way to work. Would have to pull off the road and wait, and then take off again. Thought it was either the ignition switch or the RCM. Tried soldering the three terminals on the back of the RCM. Fixed nothing, so I bought a new RCM and new ignition switch. Worked great for 20 minutes. Check engine light came back on, still the damn mass airflow code p0102. So I took it to my buddy before I just drove it off a cliff, and had him test it at the dealership, mass airflow sensor its self is good cause it's new, tested all the cables, (voltage, resistance, ext). All passed except one test failed. And so it seems the PCM is bad. So he said what is causing this is the engine heating up is making the PCM get to hot witch is causing the car to fail. Apparently it happens to alot of vehicles. So if any one has a fix for this that is cheaper than paying 2 grand for a new PCM please for the love of God help me lmao. I've had a very very hard time. Has anyone else had this issue, and fixed it by wrapping it some how, or painting it with heat resistant paint. Or relocating it. Please help!
