Have Subaru Questions? Ask a Subaru Mechanic and Get Answers ASAP
My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
One common component to cause this issue here is a fault with the crank position sensor itself.If this sensor is sending false rpm readings or cutting out the rpm signals to the ignition components and computer this issue here occurs.I would first have the fault codes checked to see what codes are set using a scan tool that will connect to your vehicle.If any codes are set the codes need diagnosed first to locate and repair the fault here.If no codes are set the scan tool can be used to check the rpm signal when the fault occurs (which will involve allowing the shop or facility to drive the vehicle to see it act up to check this signal) to see if the crank sensor needs replaced.
If more help is needed, use the reply tab to continue our conversation.
