1998 olds intrigue with a 3.8l motor. Was running great then all of a sudden died at 60 mph. Now it just cranks over but won't start. It has fuel and the fuel pump works so what would cause this?

If you are saying it starts and then dies, have you checked fuel pressure again ? Could be the fuel pump relay.

The first thing i would check is the fuel pressure. the fuel pump may be running, but that doesn't mean that it is putting out the right amount of fuel

Have you checked the fuel pressure? I think that the fuel pressure is between 55 or 60 pounds. They won't run under 52 pounds.

If the engine won't crank with compression in the cylinders, either the head gasket has blown or something else major has happened.
You will have to get it towed to a shop.
If it cranks normally but won't start, you have to figure out if it is a fuel or ignition problem.
Did the temp gauge show it was overheating before it died ?

Don't work on those but it is normal for vapours to be in the motor. You might just want to check your pcv (Positive Crankcase Ventilation) Valves ie breathers.

Cooling system--get it to your favorite mechanic befor the motor freezies up

Check the fuel line pressure it may be low should be 55lbs

My first thought, is the fuel pump quit

That is where you start, or a repair shop should start

I do not like going anywhere near 70 mph for that reason,
& I'am getting too old to enjoy speed & spend too
much time making love to vehicles, to put them under
any load at high speeds or uphills

It won't die when pulling the relay because it has another power path to the fuel pump through the oil pressure switch . Fuel Pump Electrical Circuits Description and Operation watch this video on fuel pump control , shows chrysler first , ford ,then gm . wait for gm an he explains the oil pressure switch . Plus when it won't start ,don't guess or theorize ! Test what's missing ? check for spark , no spark check ignition system , coil's , ignition module , crank sensor etc... has spark ,do a fuel pressure test etc... don't think computer , when it won't start does the check engine light come on with the key on run not start . If light is lit ,nothing wrong with the cumputer . If want to fix cars you really should take some automotive classes . Test don't guess .Watch some other videos crank no start videos etc...

this sounds fuel related to me. did the car just all of a sudden start losing power on the highway? i guess it would crank and crank, but not start when you pulled over? have you run out of gas recently or frequently? i would check your fuel filter first, but it sounds like your fuel pump just up and quit on you. that pump is, of course, inside the gas tank. pulling the tank involves 2 straps, 3 fuel lines, and an electrical connector plug. hopefully you were low on gas when it happened. that way the tank is not so heavy and hard to work with.
