Engine Stalling without warning

[uv199]

Hi,
I have a 1992 Ford F-150 with the 302 V8 (EEC-IV), approx 160,000 miles. Recently the engine has been stalling. It seems to happen after it has had a chance to warm up and I have driven it for 10-15 minutes. It will idle nice an smooth and runs well but will stall out, or stutter if I am traveling on local roads and may or may not catch itself, but will stall a few minutes later anyway. I can usually start it back up if it has been off for a minute or two but once the stalling begins it happens more frequently until the next time it has sat long enough to cool. The last time it stalled it took 10 minutes until I could start it.

I checked the continuous error codes and get 18, 41, 31, 32, 33.

18 in the reference show "Spout Circuit" and "Spark Angle Word Failure"

31, 32, 33 seem to be EGR EVP Related
41 is Oxygen sensor.

My question is: Can the EGR-EVP and Oxygen sensor issues cause stalling?

After reading some threads I suspect now that it is Spark related. Possible Ignition Module (TFI Module) which seems more likley since it runs so smooth then stalls out.

I need some advise from someone with more experience.

Thanks,
Paul
