What could it be will run for a few mins then shut off.

What is your question?

I replaced the alternator,battery,fuel filter,fuel pump,and ignition switch. It wi run at idel for 5 mins or so and spit and sputter shut off but if i try to give it some gas it spit and sputters and shuts off. I drained all gas and put new in with a gas treatment. Was giving code for flex fuel sensor saying high voltage got used one now saying low voltage. It all staryed while i was driving 70 down the hwy it just shut off tried to turn over a few times and battery died got a jump it ran for 10 mins so replaced alternator jumped started right up got back on hwy shut off before i could get any speed. Replaced battery ran at idel for 15 mins tried to get back on hwy shut off again.towed to shop only for them to tell me they cleaned some wires and ran it for an hr. Drove it short distance ran fine next day drove it about 20 miles then shut off wait a few mins crank back up drive a mile shut off waited 30 mins got 5 miles towed it home replaced fuel filter and pump now will run for 10 min
