1-Fuel pump in tank has loose wire. 2-replace pump or repair wire. 3-fuel pump relay crapping out, test first. 4-check or replace fuel filter. 5-use high octane fuel and try to use ethanol free fuel. Early model engines hate ethanol plus you'll have betta performance overall especially with Lucas gas treatment with every other tank full of gas
