1995 safari ran good then engine light came on and lost power ,acted like it was running out of gas .let set and started and ran ok?

A flashing service engine light means that there is a problem that could damage the engine emissions system.. This could be a bad spark plug or injector or many other reasons. You need to have a scanner put on the system and see what codes are are being set. AND do this asap. Most parts stores will not charge you for doing this.

Sounds like fuel pump is out and know there's not a reset best I can remember

run fault codes to determine what set off the engine light That will point you as to which sensor has a problem

with the key on engine off listen to fuel pump,if you can not hear the pump winning ,the pump is bad

if you can hear it,it might be working but create enough pressure
you can rent a fuel pressure gauge from auto store and check the fuel pressure

Is the check engine light on ?
If one of the sensors fails, the light should come on and set a code in the computer.
If not, it could be a problem with the fuel system, such as low fuel pressure.
You could be loosing power to the fuel pump relay or the coil pack.

Have you had the engine tuned up lately? Old wires and plugs will act like that.

is there a engine light on? take the gas cap of and see if it does better you might have a plugged vent

maybe your iac valve is not working? it takes place of a choke or temp sender to computer could be bad which controls t I.A.C. known as the idle control valve,do you have any codes?

check the sparkplugs also the sparkplug cables also check the coils if it's dead or not

My 1997 safari was doing the same. After being shut off for a short period of time it started as if it was flooded. If I put the accelerator to the floor it would fire up. As well, I had no engine codes to report. I replaced the fuel pressure regulator and everything is great. It was leaking fuel into the engine causing it to act flooded when starting. Once started, the computer system made adjustments for the leaking fuel so the engine ran fine. If you turn the van off and immediately try to start it, it should fire up. (don't give it time to leak extra fuel into the engine)
