1994 Subaru SVX - Starting problem

[KevinC]

Good morning everyone. I almost never write. I read (lurk) occasionally. I am a fortunate man in many ways. One of which is owning three. A 94 Laguna LSI (mine), a 92 Silver LS (hers) and a 92 Silver LSI (our son's, a wreck we hope to rehabilitate, -not our son, the car). The 94 is quirky. Starts, runs fine but won't re-start if left for about 45 minutes. If I attempt a re-start immediately or within about 30 minutes, no problem. Past that threshold no start until much later - about an hour plus. Our son's diagnosis based on reading the codes is a failed crankshaft position sensor even though it doesn't show any of the typical symptoms I've read. It's a discontinued part. I would love to locate one or another answer to this problem.
Happy Thanksgiving in these, our most interesting times.
