This is an ld issue that fixed itself and has now popped up again. About a year ago I was driving and car suddendely died it would crank but not start. They changed the crank position sensor even though it tested good because the RPMS dropped to 0 a few times before this happend it worked fine for about 50 miles then did the same thing, they next changed the icm, worked for two days then it happened again. Towed it to the shop he said ICM changed it, it ran for two days then stopped, towed it back to shop it ran fine for them they kept it a month put 1,200 miles on it and it ran fine they gave it back no charge. I used it for 15,000 mile no problem, last week it stopped brought to shop changed icm it ran fine, they shut it off and hour later went to start it for me it will not start, but cranks fine 1997 GT 3.8 N/A 340,000 I am the original owner and engine, tranny most major parts are original, PCMs etc
