My car will crank but not start. No spartk at the coil.

Customer Question

My car will crank but not start. No spartk at the coil. After trying to crank it for a long time, it may sputter and start and it sounds perfect while it idles and drives. When I drive it for more than 5 minutes, and stop at a light, it sputters then dies. It wont start again for a long time.
I have changed the spark plugs, wires, cap, rotor, coil, ignition switch, cam shaft sensor, crank sensor, acceleration(knock) sensor, battery, ecu, starter.
I have a 1996 Volvo 850 GLT 2.4L non-turbo, standard transmission.
