starting trouble

[ROSREX7]

HEY GUYS..
NEED SOME HELP HERE..
MY FD 68,000mi WAS ON A CROSS COUNTRY JOURNEY FROM CA TO NY
WHICH WAS FUN ESPECIALLY WHEN MY FD REACHED 150 MPH IN NEVADA. BUT SOME 1000 MILES LATER, RIGHT ABOUT MID WAY IN NEBRASKA I WAS DRIVING THROUGH THE CITY AND SHE JUST LOST POWER AND DIED ON ME. TRIED RESTARTING IT OVER AND OVER WITH NO LUCK. . JUST A ROUGH IDLE AND THEN IT STALLS. I HEAR A CLICKING SOUND WHICH SOUNDS LIKE AN INJECTOR. MY APEX POWER FC WAS TELLING ME THAT I WAS BOOSTING ON AND OFF WHEN THE CAR WASNT EVEN ON. I REPLACED THE BOOST SENSOR AND THE READING WENT BACK TO A STEADY NUMBER ANDY WAS .. IT STARTS UP AND STALLS AND IT SEEMS LIKE A LOT OF FUEL IS IN THE ENGINE AND NOT FIRING OFF AND A LOT OF WHITE SMOKE IS COMING OUT THE EXHAUST THAT SMELLS LIKE FUEL.. EVERY MECHANIC IN NEBRASKA HAS A DIFFRENT OPINION .. FROM ALTITUDE CHANGES TO BAD GAS
IF ANY ONE HAS SOME BASIC TROUBLE SHOOTING TIPS ILL APPRECIATE IT. I AM HOPING ITS NOT A SEAL BUT SOMETHING SIMPLE LIKE A VACCUM LINE OR ELETRICAL... NEED HELP....
THANX...
