Default Engine shuts off while driving!

Sometimes while driving, my car stalls for a moment and then the engine picks up again. One time though, it just stalled and I had to restart the engine to continue w/ my journey. At times, this momentary lack of power is accompanied by the oil pressure light coming on, but that's not always the case. I had the oil level checked and it's perfect, so God knows what the problem is.

Also, I've noticed that occasionally, going over potholes causes my oil pressure light to come on for a second. That's very odd too.

Can anyone help?

Check the wire coming from the oil pressure light too see if it has melted or worn through on something that it is sitting on. Alteratively, it could be a loss of power to part of the electrical system, on my car when the turbo timer is working the warning lights come on because only one of the two ignition circuits is powered up, must be an earth loop or something. Could be worth checking the connections on the ignition switch.

The oil=sensor wire often breaks off at its spade terminal, where it fits onto the sensor. If yours is hanging on by a thread, solder a new terminal onto it.

As for the engine cutting out, check these simple things:

(1) Are the battery terminals tight, and the battery rigidly mounted so it can't squirm around and loosen the cable clamps?

(2) Is the ground wire from the back of the alternator casing to the engine OK? These burn out with age.

If your car has never had the electrical-contact part of the ignition switch replaced, this might be a source of trouble.

A very old battery on its last leg will do that to you too. The car starts right up, but for a moment it dies... lethal on the highway with an automatic, as you lose power to steering, brakes... you gotta be quick to N and restart the baby.

Check all the earth straps on the engine especially the gearbox to front crossmember strap.
