Maybe off target but, my car just stopped going round a corner, no reason, just wouldnt start, pump primed, brant ok, most electrics, turned out to be an 8 buck fuse in the engine bay. Maybe there is a small crack? and heats up to a point of disconnection when the engine bay is idle, eg fuel stop. Brought my mighty Rex to its knees, now got a couple in the glove box.
