Great,.your still with me,..
I just be simply driving along normal 50-60 mph ( two lanes, freeway, stop signs ) and then it just quits, ( no power , nothin ), electricty is fine gauges read, fuel pump is activated. I've usually had to let 'her sit, about 20-25 minutes , & she starts right up, & runs fine,.engine bay temp seems to thaw it out... this ( leaves me worried & I just cancel my trip & head back 100 miles very worried no fun,...)

Art, just like a regular daily drive, in the last instance my distance traveled was about 100 miles, was heading down hill, ( POW !..... no power, like the engine just turned off ) the start of my trip is a 30 min. Ferry ride where I have to turn it off for 1/2 hour. i always start off topping off my gas tank ( 10 gal )
this has happened twice so far about 4 months apart. once at nite -in Dec , freaky,
most recenly last Wed. about 10 am , 50-68-degrees, sunny though.
what I don't have is the truck right now to send some photos of the engine bay.
oh yes,
I have a Mallory electronic ignition, The Dec. incident, I had to replace the sensor in the dist. ( $ 150.oo ). if you'd need images I'll go get some..
