Mine just did the same thing. I like the first suggestion. Doesn't hurt to have someone crank it over while I look through the oil fill cap and see if the rocker arms are moving.
My truck flat died on the highway, still there, and now my buddy is gonna try and help me figure out what's going on. I hope its a fuel issue, since I almost ran out of gas and then filled up, before this happened. But I will check my timing belt first, thanks for the good advise (would've never thought to check the belt first).
Its funny, that the maintenance schedule doesn't even mention the timing belt until 120,000, and then its just an inspection. Whats up with that -I know those belts are durable, but I think 100K is enough life expectancy. After that its going to leave you somewhere when you least expect it. And then there's the variables of how the truck is used, or abused if the shoe fits, weather and the likes of stop and go(abuse). Oh yeah, before I forget- BUY A GOOD BRAND AND DON"T BE A CHEAPSKATE WITH THIS PART-IT WILL COME BACK AND BITE YOU, YOU KNOW WHERE!! And while you're in there, change the water pump (I know most are external), but its a good time as any while you're bent over the grill of your favorite ride..
Most times, the belt won't snap, but will get out of time when some of the teeth break loose and allow the belt to slip. The way to check is to put the crankshaft at TDC, and then check the cam sprocket triangle being at the pointer behind the plastic plug in the front cover. You might have to rotate the crankshaft another 360 if the triangle is not aligned, but it should align once for every two crankshaft rotations.
Most times again, they also break when you go to start the engine. I guess trying to overcome the load of the valve springs at slow speeds can tear the teeth loose.
If you stop running going down the highway, I'd be more inclined to check fuel pump output and pressure first. Then follow with ignition and cam / belt checking.
It's not how hard you work, it's how much you get done. Simplificate and add lightness
