John,
I'm not sure if the pump was priming or not when this
happens. The last few times its happened I just replaced the
power supply relay with a spare and it works fine for awhile.
I didn't even think about the fuel pump until your e-mail
last night. If the new wire I installed last night doesn't
fix the problem I will check the pump operation.

Thanks, Grant
