Ok, so this is what happened.
I was driving hope the speedo stuck and the van came to a stop, would not restart.
After checking and double checking, I found a fuse had blown, replaced the fuse and everything worked, I was happy, well.... it worked for about 20 miles then the same thing happened, car stopped, would not start...So I replaced the fuse and managed to get it home.
What would be causing the fuse to blow, a week before all this started i had the starter motor replaced, could that be causing it?
Thanks
