Hi guys it's me again after more hours spent it the the hot weather I located the problem. The distributor coil winding have corroded causing a open circuit so I fitted a new one I happen to have as a spare so all if fine

Good work, I was feeling it may be fuel delivery but assuming it to be fuel injected could not comment.
