Yesterday while driving on the freeway I decided I wanted to get the best fuel consumption possible, so I drove in 6th gear for about 15 minutes straight, the longest ever for me in that gear. All of sudden, my car lost power and I saw the check engine light appear for a split second and then disappear. Then it was like nothing happened, the engine didn't die, it was like a hiccup.

This has never happened to me before, any ideas of what it could've been? Maybe I was driving too slow in 6th gear, my rpm was at around 2500, I don't think that's too low.

Thanks!

Nels,

Is your car OBD II ('96-'98)? It's possible that the hiccup you described is due to a failing/marginal O2 sensor which I've heard (others chime in here) are real bugaboos to the OBDII system. May just be nothing, and may never happen again.
On another note, I'm guessing you don't normally drive in that RPM range (yeah, I've cruised at 2500, as well) but you may also want to run some Techron, Lubro Moly, or similar cleaner through the system. Perhaps you have an inordinate of carbon buildup and the low RPM exacerbated the problem. While the fuel additives won't fix a failing O2 sensor, it can only help the general welfare of the engine. Techron a few times a year, kissing redline, and track duty are all part of my routine "maintenence" regimen.

Yes, it is 96 OBD II. Maybe I should get scanned to see if any errors came up. I'm bringing it in for the wire harness recall tomorow, I'll have them check it out.

Thanks!

There is nothing wrong with cruising at 2500 rpm in 6th (other than wanting to go faster . . .)
