Thanks, All. Sensor is the confirmed culprit after 500 k's. Not a miss.
Interesting what you said Ken. Each time it misbehaved, then cooled down, it started again.
Also thanks, Threepot, for the eBay tip. I think no T300 or T400 should leave home without a spare sensor!! I certainly won't venture far without one. Or a "Blackbox" for that matter; coil too if really serious. Maybe a trailer with an entire motor and workshop mechanic....
Just kidding - I have still to meet a workshop mechanic who is also a beautiful young woman with nymphomaniacal tendencies!
Upshot is, the advice received herein has helped us to a quick and successful remedy.
Thanks to all.
