When it dies check for spark at a plug wire , stick a screw driver in the end of the plug wire an hold near ground (metal on the engine ) Doesn't always have to be a fuel problem . Ignition modules can cause this also. Transistors in the module could be shorting out when hot . Rather then guessing as to what the problem is , test ! Fuel pressure test's too ! Do the cooling fans work , engine hot fuel vaporizing in the fuel rail . Check engine light on ?

My 99 Jeep Cherokee keeps shuting off when I am taking right turns. If anyone can point me in the right direction that would be awesome. I am really stumped.
SOURCE: Is it vapor locking or not? All else shows okay.
vapor lock just doesn't happen on newer cars that are fuel injected like yours, it was carburetor equipped cars that vapor locked
SOURCE: Acts like vapor lock
when they went to fuel injection the fuel that was not used returned to the tank thus cooling the fuel and ending vapor lock, my question is did you do a fuel pressure test? and di you do a fuel leak down test? and the first thing I would do is change the fuel filter. with ethanol in the gas it kills the filter. I have to replace mine every three months they just plug up from that junk. Other than that the only other thing would be a coil breaking down when it gets hot the coil shorts out when cool it starts so check those things first. be sure fuel pressure is 50 to 60 PSI and does not drop below 30 PSI for at least a minute, if it does the fuel pump check valve is bad, also the fuel sock could be bad as well.

1985?? you sure ,havent you heard of getting cash back on old vehicles against a new one ,no wonder poor old GM is going bust .As for engine stopping on you try flushing the cooling system out with a bit of caustic soda then refilling with water only if it works then refill with antifreeze ,add the caustic to rad when engine is cold then about 4 big table spoons should do it then run engine for 20 mins or so

Never heard of that on a buick FI. When it gets hot does it cut off and restart later? More info.
