1991 Olds Ciera V6 3300 automatic, I replaced all 3 coils and the ignition wires and plugs and the car dies after about 5-10 minutes. Just shuts down. After 10 minutes I can restart it and it will do the same thing again? :

Check your crankshaft position sensor and direct ignition system module here's how you do it.

Here is a little trick that will literally show you if a DIS module and its crankshaft sensor circuit are working: connect a halogen headlamp to the spade terminals that mate the DIS module to the coils. A headlamp is recommended here because it puts more of a load on the module than a test lamp. If the headlamp flashes when the engine is cranked, the DIS module and crankshaft position sensor circuit are functioning. Therefore, the problem is in the coils.

If the headlamp does not flash, or there is no voltage to the module or coil pack when the engine is cranked, the problem is most likely in the crankshaft sensor circuit. On most vehicles, a bad crank position sensor will usually set a fault code, so use a scan tool to check for a code. Or, check the crank sensor itself.

If its not coming from the ignition system, check fuel pressure/fuel pump relay/
