Yes it is possible to have a problem starting the engine if the transfer pump
is not functioning well and especially if the fuel has been heated up slightly
by the heat from running the vehicle.
This would be similar to Vapor Lock.
A fuel pressure test should tell you something.

Don't forget about a weak spark causing problems too! ;-)
