"Would i show the loan repayments on the profit & loss?"
No.
"and the remaining loan less the repayments on the balance sheet as a long term liability?"
Yes.
The transactions you should be considering for the loan repayments are simply to credit the bank account (or other repayment source) and debit loan account. That shows the money coming from the source of funds, and going into the loan account to reduce it.
