So the other day my 1993 f250 7.3 idi n/a will randomly get a sudden burst of power and then it starts acting like it's running out of fuel. And the other night it shut it self off and wouldn't start up again till I sprayed starting fluid in it

 

I would check for an air leak, my idi was doing the same, turns out I was sucking air through the metal line filter to ip

 

yup... air intrusion ... check ur fuel filter.. bottom bowl.. get a WIX 1 pc fuel filter ... the cross reference # is a BF 1222( Baldwin # )
