Hello, my name is***** you tell me if the engine turns completely off and then you need to restart it?
Customer: replied 1 year ago.
yes it does
Expert:  Fixitman replied 1 year ago.
Thank you. It sounds like you may have an ignition switch or relay that is causing the circuit to break. It can also be a crank sensor but that is not as common. This will be hard to diagnose since the problem happens at higher speeds. Did you plan on fixing this yourself?
Customer: replied 1 year ago.
YES I plan to fix it myself
Expert:  Fixitman replied 1 year ago.
Then I would start with changing the main relay. This cannot really be tested since the problem is intermittent. Do you know where this is located?
Customer: replied 1 year ago.
no i do not
Expert:  Fixitman replied 1 year ago.
The two main PGMFI relays are located under the passenger side of the dash behind the glove box. I can send over a picture later when I am back in front of my PC.

Expert:  Fixitman replied 1 year ago.
Hopefully that is it. I can't see how a small vacuum leak would cause this but you never know. Please keep me posted. Thanks.
