IS IT ACCEPTABLE TO REPEATEDLY PRAY FOR THE SAME THING?

Luke 18:1: And he spake a parable unto them to this end, that men ought always to pray, and not to faint - give up; Saying, There was in a city a judge, which feared not God, neither regarded man: and there was a widow in that city; and she came unto him, saying, Avenge me of mine adversary. And he would not for a while: but afterward, he said within himself, Though I fear not God, nor regard man; yet because this widow troubles me, I will avenge her, lest by her continual coming she weary me.

And the Lord said, Hear what the unjust judge says.

Jesus here give an example of a woman coming before a judge continually to get what she wanted and did so until he finally relented and granted her request because of her perseverance.

We can and should do the same in our prayers to God, to come before Him with confidence seeking an answer to our prayers.

Luke 18: verse 7 goes on to say: ...shall not God avenge his own elect, which cry day and night unto him, though he bear long with them? I tell you that he will avenge them speedily.

Now notice verse 8: ...Nevertheless when the son of man comes, shall he find faith on the earth?

Good question, when we ask we must believe that we will receive an answer or none will come. The answer might be not at this time.

James 1:6: But let him ask in faith, nothing wavering. For he that wavers is like a wave of the sea driven with the wind and tossed. For let not that man think that he shall receive any thing of the Lord.

We repeatedly ask the God's Kingdom come do we not? We daily ask that He provide us with our daily bread, do we not? He expects us to repeatedly ask Him for all that we have need of at any given time! His ears are always open to our requests made in believing faith!
