Engine randomly died out… but restarted?!?

[Dickinson County Comanche]

I was driving in town and was coasting down to a traffic light but wanted to put in some throttle to make the shift nicer, only to realize my engine had died. It did pop out the exhaust a little, which makes me think it was spark-related vs fuel related, especially since it died so quickly and suddenly. It started back up and idled at like, 2,000 rpm for maybe 10-15s then has run fine. Not down on power, no missing, popping, nothing. Back to normal. My guess is CPS, it’s original, but I tested it a few years ago and it tested fine, above the minimum voltage. Maybe it’s finally going out? It hasn’t had any issues with long crank/hot starts, and it wasn’t particularly hot when it died. I’m also suspect of the ASD relay, but I think that kills fuel, not spark. Not entirely sure, figured I’d get some inputs before shooting the parts cannon.

Check your manifold bolts they like to come loose and too much air when decelerating can cause the engine to shut off. Those loose bolts will also cause an intermittent high idle.
