Exclamation Help! Crank no start, not fuel, no codes!

UPDATED! I really appreciate any input on this!

cranking good, but not starting. New fuel pump, new battery, tested 2 keys so its not the key.

For the last year there were times when my car would not even crank over, seemingly at random. I realized that if I unhook the battery and let it sit for a few minutes, then reattach battery, and turn the key, it will restart. Sometimes I had to wait longer than others, but never longer than 20 minutes. This was very rare so I never really messed with finding out the prob.

Jump ahead to a couple weeks ago when I posted this below:

A couple days prior to not starting it would crank a few times, and after a while eventually start. Then one morning dead, swapped the fuel pump, and verified fuel at the injector rail. I've now tested the coils, which all test .08.

Any other possible culprits besides crankshaft sensor?

I finally take the car to the stealer, who didn't have any codes or clue as to what the prob. was. They say they replaced fuse 67 for the immobilizer, and mentioned something about maybe one of my keys needing replaced (although both will start the car now). They were as confused as me but it was starting so I took it back (and paid them 180). The next day parked on a flat spot my car was doing the same thing, cranking but no start. I let it sit, didn't disconnect the battery or anything, and in about 20 min, cranked and it fired up.

No problems for a few days now untill today. I was parked on a steep incline, facing up the hill, and my car was totally dead, no lights, no crank. I was confused. i put car in nuetral and repositioned so I was facing downhill to jump start, but halfway through my turn, my dash came alive, I cranked, and it started.

I would appreciate any advice so that I don't get stranded somewhere, and since the stealer is confused too, I don't know what to do next!

Thanks for any advice!
