It could be lose ehuset system parts or catalic conveter problem but itsan 86 thats 25 years old but i have an 85 ford ranger and it still runs great look for things that are lose or moveing around exhust system

Ur truck's fuelpump needs an attention.

Tune up?

Have you checked it for spark when it dies? It sounds like a bad ignition module.

check your fuel filter

If it's not getting fuel check the interia switch. There is a label under you hood that explains "If vehicle fails to start". The switch is on the passenger side kicker panel behind it. If it accidently getting kicked by a passenger it can turn the fuel pump off. Just check it happens all the time to Ford owners.

This year of ranger had a few flaws, In one case, a break power booster was robbing the vacumm, you can test this by plugging it off and seeing the differance, but you will have limited brakes. This model year had a problem with a vacuum leak on the manifold. You can check these in many ways, but please don't use starting fluid. The rear of the manifold usually on the drivers side where it seals to the block.
Also, in 2 other cases a cracked head has gave me the same problem. It is caused from a loss of vacuum.

check your cat convertor

IT LOOKS LIKE YOUR FUEL PUMP IS GOING BAD
