driving today at 65 mph. suddenly the radio blacked out, the locks starting cycling multiple times, the gauge needles just bounced back and forth between the stops and I had zero power when i pushed gas pedal as if the truck had shut off... after rolling about 1/10 mile everything went back to normal as if nothing had happened at all. the gauges stabilized where they belonged and the radio came back on... I have had this truck for a month. (bought it used with 134k miles) And just got out of hospital from appendectomy so last thing i need is to be stuck on the side of the road or a major repair bill... any suggestions for the cause?
