then I slowed to 70mph. A few seconds later it began slowing down. I pulled off in the grass the other to the right of the emergency lane, popped the hood and the primary filter was empty(Took the filler cap off and got no indication of vacuum OR pressure). The engine never did quit. Closed the hood, sat a minute or two and got back out on I-40. ran it back up to 70 for another 10 miles and it slowed down a couple times on it's own. Stopped to do some errands for a half hour or so and proceded back home with no further issues. The trip home was 45 miles but the speed was 55mph or slower.

Opened the hood and the filter(primary) was3/4ths full. You folks ain't gonna tell me I have an IP going on the fritz, are you??

No further starting problem since ridding the vent hose of it's tenants. Filter has plenty fuel in the mornings.
