My car (a '93 945T with ~ 140,000 miles) has died a few times while driving down the highway, maybe once or twice a month. I'll be driving along, and the engine just dies. I'll pull to the side of the road and it won't restart immediately, but if I let it sit for a few minutes, it'll start up and run with no problems.

It's not the crank (RPM) sensor, I just installed a new one a month or so ago (thinking that was the problem). The dying problem happened before that, and after.

The codes from the engine diagnostics are:

#2 sensor: 312
#6 sensor: 144

These are the same codes I pulled from it before I changed the crank sensor (and then cleared the memory).

Code 312:
Fault Condition: Signal missing for knock-related fuel enrichment
Causes of Fault: Wiring break between EZK terminal 4 and FI #28

Code 144:
Fault Condition: No load signal from fuel injection system
Causes of Fault: Bad fuel injection relay; faulty wiring from LH to EZK; bad LH module

Based on this, I'd say the thing to do would be to replace my fuel injector, but I wanted to run these symptoms by this board to see if there is anything else I should look at.

Also, what does "Wiring break between EZK terminal 4 and FI #28" mean? I don't know what the EZK terminal is, I assume FI #28 is my fuel injection system.

Thanks!
