I'm losing track of all this now but has the ignition coils and spark plug leads been swapped/changed?????? Ignition coils fail when hot the same as crank angle sensors, have the coils primary and secondary windings been metered yet?

A crank sensor will cool down fairly quickly and allow a re-start then fail again when it reaches a certain temperature!
And when it fails it kills the ignition system as the ECU has no reference to the Crank position, this replaced the old mechanical points, and when the points closed completely there was no spark as there was no pulse, when the coil fails on the sensor it's the same! "No pulse, No spark"
