1996 Mitsubishi Eclipse GS Auto 2.0

I just got my car back after a year and a half in the body shop. I think those guys fried my PCM. My car will start and will run for about 15 minutes and then turn off. I tested and measured the impedence of the coil and it checks good. Now, when I compare the readings on the harness when it runs and when it doesn't, I find that I do not see me pulses on cylinders 1 and 4. To verify my findings I attach a spark plug to each ignition cable individually and sure enough 1 and 4 do not fire. The engine schematics show that the harness is directly coming from the PCM. The strange thing is that after about 15 minutes with everything off the engine will fire right back up with no problems. Then 15 minutes later it dies.

I need help with the following questions:
1. My manual shows that the PCM is located in the engine bay next to the fuse box for 1996 turbo models. It shows that the ECM is located under the dash behind the center console. Well I have both pictured items so what is what?

2. Does my problem sound typical of a bad computer? Running the check engine diagnostics I get the following codes. 11, 12, 43, 53.

3. Can anyone offer any more help in troubleshooting that I may have missed?

I appreciate everyone's help with this.

Thanks,
Robert

the computer is located under the dash on the passenger side, try replacing the plugs, make sure all your plug wires are hooked up correctly, if they are wiggling loose when the engine is running that would cause the engine to die, umm, make sure your fuel injectors are not plugged or cracked, its mostly process of elimination
