can drive this truck for an hour sometimes with no problems and other times it will shut off 10 times in that same hour. The guages will all go to 0 and back up over and over while driving, mostly shuts off while pulling out of a stop sign seems like trans slipping then shuts off. When it shuts off it acts like I just shut the key off... no bucking or trying to run just instantly dies. Wait about 10 seconds and the dummy lights on the dash light back up and it will start right back up. also sometimes it will do it while trying to start it... it will turn over for a split second and then act like you shut the key off. Wait a few seconds and try again and it starts right up. I already replaced the ignition switch, crank shaft sensor, transmission control, transmission input and output shaft sensor. All relays.
