Hey, I have a 91 4r and mabye once a day as I am driving at speed the truck will seem to loos all power and the dash will light up (engine light oil light etc.) But only for a split second. It feels like a slight hesitation, happens all the time and never causes the truck to stall or anythings just a little shudder? Anybody come across this?

Thanks,

 

It almost sounds like a bad ignition switch. Or the connection to it.
