have a grafted yellow passion fruit vine. This is it's second year. Plant looks great, 100's of flowers with bees aplenty. Flowers just fall off, no fruit forming? Is this normal for 2nd year?

most likely answer is lack of boron. In addition to regular use of complete fertiliser such as Dynamic Lifter Advanced for fruit and Citrus, use Yates Trace Element Mix every 3 months, or every two months if soil is very sandy. This should help the flowers hold, as will avoiding fluctuations in soil moisture.
