My Extreme has everything shut off going down the road...Gauges and and power and engine...it's like I shut my key off. I have changed my fuel filter and pump and spark plug wires. It starts right back up easily. It is a 4 cyl with 56000 miles on it. The engine light has hardly ever come on. I did take it to a mechanic when it did and they said it was the trans slipping so the flushed it but said thats not whats wrong with it. There were no other codes showing up. What could it be?
You may have a faulty electrical component. When it heats up it breaks connection within itself. And when it cools down connection is reestablished so Your truck starts like nothing has happened. Good Luck.
