two possibilties

1. overvoltage protection relay=check the fuses on top of it-if faulty- replace it/them. location of relay is behind the battery,and behind the plastic cover-to get an idea of what the realy looks like -go to the fastlane section of this website and do a search on the online catalogue-you will be able to see pictures of the the relay.

2)faulty fuel pump relay.

good luck!
