cam and crank sensor help

I was having issues with my engine, idling rough and having no power in gear. Replaced Crank and Camshaft sensors as well as throttle position sensor. New plug and wires, Ignition control module and the Engine control module(the Computer) none of that fixed the problem. Finally replaced the ignition coil Adapter (which on my car is basically the distributor) this worked. the car ran absolutely great, had power, engine was idling very smooth. Then today on my way to a dr appt I suddenly lost all power, RPMS went down to zero, car did not die. Got off to the side, shut it down and it would NOT crank back over. engine would turn but not crank. Code scanner pulled Crank position sensor circuit malfunction and Cam position sensor ckt range/perf.

both of these sensors are brand new...
both still under warranty so replaced both and again car is running great...afraid to drive it because i don't know what caused them to go out. all wiring looks good. should i be worried about new sensors going out again and what could cause them to go out again
