Srarted the break in process today. Ran through 2 tanks of fuel then went to take it for a ride on the third. The truck went about 10 feet then stopped. kept running but stopped moving. I shut the truck down fooled with every wire then it was ok. Started it up and it did it again after about 5 seconds. Shut it off. Played with wires but this time I got nothin. Any ideas?
