2002 chevy tahoe sputtered and shut off while driven nothing comes on message box.it didn't start doing this till I got gas in southcarolina

it is a distinct possibility as some dealers use a E added fuel to rip motorists off. It is also a possibility that there was water in the fuel so I would have the fuel filter changed as a precaution. Run the fault codes to check for reported faults.

It could be the fuel pump. The pump is in the gas tank. The pump is actually cooled by the fuel. Occasionally, in hot weather, when the pump starts to get old, if you run the fuel tank very low, the pump will heat up. Then, when refueling, you are putting fuel in the vehicle that comes from underground at about 50 degrees F. This can cause the pump to fail.

Might be a bad fuel pump

run the fault codes and look for a venting problem with the canister.

try some fuel additive that removes water and cleans injectors

You r prkb liw kn freon , u need to purchase a bottle of 34 a freon from any auto store.read the directions if u can't figure it out go to you tube start the vehicle turn the air on high put the quick valve on ur condenser unit push the button on the bottle your vehicles air should get cold keep bottle on till empty take quick valve off dispose close hood enjoy ur air

check fuel pump relay, on start up, relay is bypassed, allowing a start, but dies when runs out of gas.

Fuel filter. Timing/timing chain. Idle air control valve. Idle sensor. Vacuum leak. Probably one of the above, but the filter is cheapest place to start. Change your air filter too, if you haven't for a while.

oil pressure drops when rpm's drop to .well..zero...so no... oil pressure is a result not a cause likely....did you overheat it ? drive it to 107mph and have the rev limiter kick in? does it start and run now ?
