I have a few questions. First off my check engine light is on. The car is obdI and uses mil blinks to indicate codes.I know how to access the ecm to make it generate the codes but I dont have anything to refrence them too. What codes are what? Second when I start the car it runs perfect for about 30 to 60 seconds. After that time it sill stumble and stall quite abruptly. Any suggestions on what it might be or where I can find a print out on what the blinks mean? Any help is much appreciated.
Do you
have the same problem?

11 IGN reference signal.
13 MAP sensor pneumatic circuit.
14 MAP sensor electrical circuit.
15 Vehicle speed/distance sensor.
17 Engine running too cool.
21 Oxygen sensor circuit.
22 Coolant temperature sensor circuit.
24 Throttle position sensor.
25 IAC motor driven circuit.
27 Fault in injector driver interface circuit.
31 Purge solenoid circuit.
32 Fault in EGR diagnostics.
34 Speed control solenoid circuits.
33 A/C cutout relay circuit.
35 Fan control relay circuit.
41 Charging system excess or no field current.
42 ASD relay circuit.
43 Fault in ignition coil control circuit.
44 Battery Temp Voltage.
46 Battery voltage too high.
47 Battery voltage too low.
51 Oxygen feedback system stuck at lean position.
52 Oxygen feedback system stuck at rich position.
53 Internal logic module problems.
54 Fault in the distributor high data rate pickup circuit.
55 Completion of fault code display.
62 Indicates unsuccessful attempt to update EMR mileage.
63 Unsuccessful attempt to write to an EEPROM location by the controller.

Possible causes:

Dirty fuel injectors (cleaning the injectors often fixes this).
Bad MAP (manifold absolute pressure) sensor
Bad TPS (throttle position) sensor
Bad or dirty MAF (mass airflow) sensor
Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
Bad gasoline (fuel contaminated with water or too much alcohol)

Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

Dirty or worn spark plugs
Bad plug wires
Weak ignition coil
Wet plug wires

Had a new development. The car now has no spark and no injector pulse and does not run at all. Cranks but does not start. I have replaced the crank angle sensor, maf sensor and power transistor unit with no effect. I have checked the mfi relay and it is fine. I have also checked for fuel pressure and power to each of the sensors (both are fine). Lastly I removed the ecu and checked the board. I know the ecu's in these cars have problems with caps leaking but I found no problems. I tried to access the flash codes in the ecu by cycling the key three times leaving it on the third time but the only responce I got was the light coming on for a few seconds and then shutting off like normal. My only conclusion after all of this is that the ecu might be shot without there being any defects obvious to the eye. What do you guys think?

Found the problem. Inspected the ecu again and found one of the caps was leaking. Removed the bad capacitor, cleaned the board and installed new capacitor. Car started right up first try.
