My 94 integra Ls stock engine has been shutting off on me when i less expected like this morning while on the highway for 5 minutes at 55 mph shut off, i pull to the shoulder and 30 seconds later started like nothing ever happened after that i drove another 15 minutes with no problems at all. before that, specially when hit bumps on the road, shuts off but since is in gear (5spd) comes back on.. is a weird problem no cells on or noises. my buddy susgested to replace the fuel pump relay which i pulled out and is a RZ-0132 relay im not even sure if this is the factory relay on this cars... any help appreciated

 

main relay or ignition control module

 

The PGM-FI Main Relay is a common problem on older Honda/Acura, there are more then a few treads about it, a search would have found a number of them.

If you know how to solder and have a solder gun/pencil, your symptoms point to the relay as the problem, it's almost always a simple fix...

you dont technically have to remove the old solder, you can flow new solder into place if it is lacking, i usually flow silver flux core solder in weak solder joints on old pcb's to fix problems like that. My old dodge neon had a similar problem with dry joints on the back of the gauge cluster that used to cause the speedo to die while driving. Easy fix. I did the same thing on the main relay too of my teg.
