Don’t jump on the first time

Hello again.My Ford with 101Ps and year 1999 does after a longer ride approx.300-400Km and a rest overnight no facilities to jump again.I have so 10 times turn and have the feeling he gets no diesel.Then pause 2-3min. key turn around and he runs.My question about what can be that. Are the distances shorter no problem with starting. Greetings pornler
