Mistery [non]start issue ...

[BP 15LR4]

I am having this very same problem as we speak and I came across this forum while researching.....have brought it into the dealer 4 times now....they still have it. I have tried all/most of the "solutions" proposed above with limited success. It has happened to me about 5 times in the past 2 months. Dealer claims everything checks out fine....then they find something that "might" have caused it, then it happens again.....very frustrating.....has anyone actually had a documented resolution/fix to the problem?
Thanks

UPDATE - after a month of retrieving my LR4 and then returning it a couple of days later because the problem would re-appear, it seems the dealer finally solved it......it was a defective fuel-pump motor. I've had it for 2 weeks now and not a single recurrence. Fingers still crossed
