Hi greenie
I don't think there is a link between the oil pressure switch and the fuel pump relay, sounds like the 12v ign supply is being lost. Check the battery terminals are clean and tight, with the engine running wiggle various wires to try to recreate the fault. It could be the fuel pump relay  .

Hi Greenie

I had a similar problem with my Mk1 Cabby and it turned out her immobiliser had got damp and was trying to cut the engine - not fun at 60 mph - new immobiliser correctly fitted solved the problem - worth a look if it keeps happening!
