I had the same problem-my check engine kept coming up with crank sensor(replaced several times- the car would run for 2 days then stall again)finally checked and replaced the wiring harness and the car ran great for awhile. Now I have a whole new problem(abs lights started coming on and the gauges all died while driving at which point the car just stopped and woulkd not restart)thinking alternator(the battery works great in another car)
Sounds to be a bad ignition module or one of the coil packs. Will need a scan tool to know what cylinder (s) are misfiring in order to narrow it down.
What I'm thinking is that the ignition module is getting hot, shutting car down, won't fire right if you immediately try to start car, and then after ignition module cools down, resistance from heat is lowered to normal value and voltage pushes on thru normal resistance and car starts. However, I not only had this happen, but also what I'm bout to type causing same exact problem: One bad coil pack can cause this problem. If you can find out what cylinder (s) are misfiring and switch coil packs to watch and see if the misfire moves to the cylinder (s) you swapped the coil packs to. Best bet may be to go to a junkyard and get module and all 3 coil packs. This may be the cheapest route to go if you can't do the swapping coils as I described above. Good luck to you and defineatly keep me informed on what's going on.

thanks for the responce. I'm a mechanic also, module is a possibility ? only fires wrong when it stalls and I try to restart. does not misfire at all when it runs normally. it is definitely a heat up problem ( something is getting hot and shutting down ) been a big problem I've had for many years, how to test modules ? or some of them for that matter. both crank sensors have values, as does the cam sensor, fuel pressure is right on. cools down and restarts and runs fine, heats up an dies, shuts right off. thanks for your help, Guy
just to let you know, what I found was that the module was bad, boy, some people here aren't going to be able to use this info, but the wiring harness from the rear crank sensor to the ingition module was burned through from laying on the exhaust crossover pipe. whoever worked on the car before ( someone pulled the heads before the cust. stated ) didn't route the wiring correctly and it layed on the exhaust pipe and melted it and the wiring crossed. spliced in a new section, sealed it, new module and away the car went. no coil problems as I stated before, didn't have any now. thanks for the input. kinda weird thinking about it, the 3x and the 8x's ( from the CPK sensors ) readings worked when I was checking data stream.. this probably won't help anybody here, this one was a little different.
