Default 1986 6.9L issues

Ok to start my truck was running fine then yesterday it started dying on me when it had plenty of fuel.

Today, it died 8 times with 7 miles.

It sounds to me like i have fuel issues.

Any ideas what to look for?

Change fuel filter If you can check the fuel pressure at the filter would be great.

But by what you described I wouldn't be surprissed if your injection pump is wearing out

I had two lift pumps go bad on my 6.9 when they went out there was no restarting
