My SUV is not cranking after it has rained, almost seems like no gas on 2002 Cadillac Escalade

The truck is running it is raining, but after it is shut off and the kids I try to return and crank it up it will just turn over and wont crank. It seems like it is not getting gas. Then the next day the truck will crank up and have no problems
. The only time this happens is when it is raining.
