My truck lose power and the check engine light comes on but not all the time. I took it to the shop but no codes or error found.It been 2 months since my PM services and I don't drive a lot. The check engine light will come sometimes and can't go over 55 miles per hour. What is the problem with it?

[1.Check the fuel filter for level.
2.remove the check fuel valve on the fuel filter housing ,clean the ball & check for roundness.
3. algea in fuel system.
4. turbo valve for sticking or crrect operation.
5. If it happens when raining check bchm,ecm.
6.Check for corrosion on ecm terminal pins,terminals that might be under the coolant overflow tank for leaks causing corrosion on any terminals
7. fuel tank brether hole for pluged by insects.

Good luck.
