Who socketed the ECU?

I had this happen. Go to your vault and set up a password. Took me forever to figure that out since it had been a while since I updated my software.

Hope that helps.

my tuner chris miller racing, he also told me it could be bad grounds or power

It sounds like it could be a socketing problem. I would have the ECU checked to make sure the soldering is good. Also make sure that the main capacitor was replaced as it could give intermeitent faults before a complete failure.
