Have a 95 e 350 5.8, starts ok, then after driving a short time, when you get off gas the engine kinda mildly surges and almost dies, then eventually dies, restarts fine , but, idle is really low and pulsing, it will usually die whenever you get off pedal , driving at normal speeds there are no noticeable issues, only when off gas. I changed the idle control valve, new plugs, wires , cap, rotor, pcv. This ting runs pretty damn good otherwise, especially since it has almost 300,000 miles. Any ideas?, do in tank fuel injector cleaners work/ help. Thanks.

Your problem sounds related to a vacuum leak. You SHOULD also have a check engine light on--do you? Check ALL the vacuum lines, be sure to take them off and look for small holes.

Check for vacuum leaks. With that many miles, chances are there is a dry rotted vacuum hose or the intake is leaking. To me it sounds like the fuel pump is going out. Here is a guide to help see if that is the issue. The fuel pressure should be about 48 PSI,
