Hello everyone, i hope someone can guide me in the right direction. I have a 1988 420 SEL, the problem i have is that the car starts up fine but when its on the road, it completely shuts off and all the dashboard lights light up and the fuel economy guage goes to red. After this happens, i have to restart that car and that seems to work until the next trip.
any tips? suggestion?

 

how long before it shuts down? and do you have all the instrument lights on? or that goes out to?

 

fuel filter?

 

the lights stay on

 

fuel pump relay.on 126 models normally located on driver side behind bulkhead near the fuse box.

 

so lights stays on . and it starts back up soonest you pull over?

 

sounds like glitching fuel pump relay, but does it take the same amount of time each shut off or is it erractic and random
