I had another make of vehicle do that, turned out the previous owner disconnected the ground for the reverse lights, verify all rear light operation with vehicle off but key on and see if they work.

Yes but hard to say when won't start I replaced the crankshaft POS. Sensor and sort of fixed the problem... Now I have put about 6oo more miles on it and when I'm driving on the highway or even in town last night cruise on or not the rpms cut out and drop right below the 1000 rmp mark and I tap the pedal and it brings it back and couple days ago when I would hit a bump at 80 mph on interstate I d notice a sudden short loss in power must be a wire issue is what you would think but the seem fine

I'd verify that your crank sensor connector and wiring is in good shape.

Also keep in mind that after a crank sensor replacement, you'll need to have a crankshaft position sensor relearn.

I doubt that the crank relearn is your problem but just putting that out there.
