Default RE: I spoke to soon

I put new ECM in and it ran good while driving it around for about 30 minutes. The next morning after running it for about 10 minutes it went back to the same problem: When I give it gas it dies!

I believe it got a power surge of some kind to the ECM (probably damaging it again). Any suggestions is appreciated!! Thanks!

I believe new ECM gone again. Poor pulse again. Any suggestions is appreciated!! Thanks!
