ENGINE POWER LOSS

2003 Vauxhall Signum

Engine Performance problem
2003 Vauxhall Signum 4 cyl Two Wheel Drive Manual 12000 miles

Driving on Motorway around 60-65 in Cruise.
Cruise dropped out and Engine Power lost - manage to pull over. Engine would not restart. No dash board indications (apart from an O2 sensor light that has been on for some time). When trying to restart, key turn but Engine does not turnover - tried spare key as well. Restarted after about 20 minutes
Battery seems ok
Have three codes
0138 - O2 Sensor
0601 - Control Module Memory?
0038 - Heater Control Circuit
Would appreciate any thoughts
Thanks

Replace the faulty 02 sensor. I would also check/clean or replace the CKP (crankshaft position) sensor
