Hello,

This sounds like you could have a problem with your vehicle's Ignition Control[IC] Module. To be sure though, I have included in the diagrams down below a diagnostic troubleshooting flowchart from the vehicle manufacturer for your vehicle for you to go through. Please go through it and get bak to us with what you find out.

Thanks,
Alex
