Can't necessarily explain the low oil pressure light. Apart from the fact the engines stalled. So if you've say disengaged clutch once engone cuts out oil pressure will drop instantly. As for the main problem cutting out. Sounds like a faulty ignitor. Although they are available separately. It's usually a case of replacing the dizzy. Usually will throw code 15. Ignition output signal or something similar. Seem to fail around the 100k mile mark for whatever reason. Read that code first see what it's saying before jumping to any conclusions but likely the dizzy from what you've said.
