Ok, 3 mechanics have looked @ truck plus 1 diagnostic center and all have failed to locate the problem. Have replace many parts & still have the stalling problem. Starts up good then approximately 5-10 minutes later motor shuts off. I mean completely shuts off. If I try to start it up right away, no can do. Have to turn off the motor, wait @ least 2 to 3 minutes turn on switch, wait for fuel to work about 10 seconds then it'll start right up.
