Delta 88 with new CAM interupter, timing chain.

Delta 88 with new cam interupter, timing chain, cam sensor, crank sensor, harmonic balancer, mass air flow sensor, tps, ignition control module, and coil pack. Second set of ignition module and coil pack! Car runs fine for about 100 miloes then starts stalling while driving, it starts right up the first few times then takes longer and longer to start. When it stalls there is no spark at the plugs. What could be causing the module/coil to overheat after the 100 mile area is reached. Can ecu do this
