Urgent

I have a honda pilot 2004 and it starts and runs
normaly and in about 10 or 20 minutes it shuts
down on its own. I try to start it up again but it's
like there's no gasoline in the system even though
it has a full tank. I checked the pressure system to
see if the gas pump was bad but it was fine. So in
that proces it finally turned on and it kept doing the
same thing. So I decided to change the crankshaft
position sensor but it still did the same thing. Can
someone tell me what to do?
