I have a 92 940 with 170,000 on the clock , the cars runs perfect but within the past 6 weeks every once an a while I will be driving and the motor will just cut out and most of the time I will pull over and it will start back upand won't do it again for a few days or sometimes a couple of weeks I was thinking it could be a harness problem maybe a bad connection any info would be greatly appreciated!!!

thanks

john
