Lately or a few times a week for the last month or two, my car will just loose all power, the check engine light will come on as well as the traction light and doesnt want to go anywhere. I have to turn the car off for 10 seconds then it runs fine and the check engine light goes off after like 3 or 4 starts. What causes this?

check all your fuses and/or spark plugs.

I've read mbc have caused a few other people to go into limp mode. So that could be your problem.

Ask/borrow someone's obd2 scanner. No use wasting time guessing. Obd2 will narrow it down for yah.

How much boost? we've had cars go into limp mode when its to high. but if it does it that often why are you waiting to bring it in. you could be doing some damage.

Its most likely the trustfull which is your measurement of air. I had a new intercooler installed and what it is the ECU is trying to match the torque to the air and because the airflow is off it is telling the ECU that something is wrong. You are probably pulling a 1241 and 1320 code. Have you made any changes since your tune. If it is your boost than you are at a point where you are causing too much boost and it falls outside of your tune...
