'98 Honda Accord Dying?

Just had the oil changed last week at one of those “Quikie” service providers. Have used them before (same location), with no subsequent issues. Until now.

While on the freeway (70 mph, or so), engine hiccups, OR shuts down completely (CAN restart in “N” while coasting). Dash lights flicker, as key is in “ACC” position, and both RPM, and MPH drop to 0 (even though, I’m still coasting). Don’t want to assume my recent trip to the “Pro’s” has caused this, but my third eye is twitching!

168K miles, auto trans. Any takers?
