This issue is most likely a leaking fuel injector oring seal or injector itself, can be verified with fuel pressure guage,with guage hooked into fuel rail, key on key off key on key off ,then pressure should hold and not dissipate over 5 mins time,if it does dissipate then use a very bright pen light flashlight in a closed garage with lights off and inspect fuel rail and injectors for wetness,also check front and rear of intake manifold,as could also be a leaking fuel line or hose. DO NOT DRIVE THIS VEHICLE until it is repaired as it is a SEVERE FIRE HAZARD. Please accept my answer, if you have any further questions I will answer them until you are completely satisfied with my answers.
