I suspect my starter solenoid is acting up on my 7.3 Diesel with 265,000 miles. What confuses me is it only quits working when the motor is at normal operating temps. Shut it off it won't start again. Let it cool for 2-3 hours and it cranks right up. I've never seen the solenoid be affected by heating/cooling cycles.

Anyone else?

By the way, in case you missed it, Jeremiah was a bullfrog.
