hey new to the forum here.... i am working on a friends 93 park ave ultra with the supercharged motor in it.... it is having a problem cutting off by itself after it gets warmed up.... if u crank it when it is cold it cranks and idles fine but once its warmed up a bit it starts cutting out and cuts off most of the time it tries to stay running but usually cuts off sometimes it will crank back up and other times it will just act like it is going to crank and doesnt.... i have checked the fuel pressure and it stays between 40 and 48 psi.... one thing i tried once it warmed up and wouldnt crank back up at all i unplugged the mass air flow sensor and it will crank up but will not idle i can keep it running by feathering the pedal but if i plug it back up it wont crank at all even if i pump the gas..... just wondering if the mass air flow sensor is the problem i dont want to buy it if its not the prob b/c its 113 bucks and money is tight but i need this car running.... any help would be great

 

It's a good possibility.
