So I was on the road today all day ('05 Baja turbo A/T, ~86,000 miles) and suddenly the cruise control shut off and wouldn't resume (wife was driving at the time). Simultaneously, the ABS light lit up on the dash and wasn't functioning. It was blizzarding and slick for most of the trip, so yes I'm sure the ABS wasn't working.

At a fuel stop a few miles later, I checked fuse 18 because it says it's for both ABS control and cruise control, but it was fine. So was every fuse I pulled in the cab block and every relay and fuse under the hood. Another stop in ~50 miles didn't reveal anything or fix it.
Then, about 250 miles later after a third stop, the ABS light stayed off and it's working again. The roads got genuinely slick by that time so I didn't try the cruise.
What in the world happened? Anything I should spend any time thinking about? I'm at my destination for a couple days and then I'll make the return trip home (~500-550 miles). Thanks for any help?
