1992 Nissan 240sx
SR20DET BLACKTOP STOCK

Strolling down the highway after work, going about 60 or so, and I just feel this loss of power. Well the cars in 5th gear, all electrical items are in working order, lights are all working, but the motors not running. Same feeling as when an alternator goes bad, just stops running while in motion. Pull over to the side of the highway, crank crank crank, about 10 revolutions and it doesn't wanna start. Get out, look at wires in the bay, and fuses and such, everything's good. Get back in, try to start it and it starts. Probably about 3 minutes later it does the same thing, motors not doing anything no matter how much I press the pedal.

Once again I pull over, crank it a couple revolutions, nothing. wait a little and try again, nothing. Now i try it once more and it starts again..Just enough to get off the highway ramp and around the corner to a side street, where yet again, it shut off..

I try to start it here on the side street and nothing..wait a little, and then it starts up again, I let it idle, which seems real off, floating around 500-700, bouncing up and down, sounds like its missing ina way. I pull injector plugs too see if it makes a diff, they all changed idle when pulled. A few mins after letting it idle a bit longer it shuts off yet again..attempt to start, and its a no go. So there she sits. Any ideas?

Last night during a crazy rainfall I had sputtering issues, and it didn't want to start. Now this morning it started fine, but my rpm gauge was working intermittently, jumping all over the place and such. Now after work I'm having this shut down while on for a few minutes issue.

Could this possibly be the ecu failing?
