That engine didn't die in that 20 mile trip, it had an issue before then. That 20 miles was just where the issue then became noticeable. What the OP also needs to find out, were any of the codes being cleared dealt with oil pressure. The oil pressure had to be low; no oil going through the filter and bypass destroyed it would have to impact the oil pressure reading.

The bypass (separate component) is there to save the engine if the filter does get clogged. Seems much more likely that the engine was making metal and that the filter issue was a consequence, not a cause.

Agree that the vehicle very likely had these issues prior.
