Starts ok runs a few minutes but pops thru intake at acceleration if I unplug mass air sensor restart runs great for a couple of minutes with plenty of power but will start to act up shortly after thanks for any help!

Seems like the MAF might be the one causing the problem. Try cleaning it with MAF cleaner and retest. Check for trouble codes.

Check the fuel pressure.
Have the computer scanned for trouble codes.
