500 SEC died, need help to resuscitate

Driving home yesterday, for about 2 minutes the car ran really rough, no power, then died. Can not restart. Most of the fuel system in this car is new: fuel pumps, fuel distributor, fuel pump relay, idle control box, idle control valve, fuel filter, fuel injectors, also new ovp. Could this problem and symptoms be related to the ignition coil? How do i check? It just cranks and cranks with no result. Also, a lot of noise that seems to be coming from the cruise control box (I think! Box on front of motor with a lever coming out of it going to throttle body.). Could the cruise control box affect anything?
