not sure what exactly you mean, if its losing power though your cats, pre cats could be clogged up, you could either remove them and unclog them or just take them off all togeather, depending on where you live.

I cannot drive car as after starting it, it will die as if it is out of gas. Mechanic checked it out and said I was not getting 12 volts out of MAF and there was a poor pulse on the injectors. Any suggestions is appreciated! Thanks!!

Was there any work done on the car just before this happened? It sorta sounds like maybe you've lost a ground connection some where near the relays. Or maybe it's as simple as a bad maf relay?

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!

If the car is eating ECM's I would start checking for shorted wiring and components, also check the voltage while the engine is running, low voltage will affect the capability of the ECM to handle inputs and outputs, high voltage could smoke the ECM.
