Sounds like fuel relay located in fuse/relay box. This is a common problem on the 944, always good idea to carry a spare.

Just on a hunch, it might be the anti theft system. Check out this link and read up on these systems.

97 GC 4.0 starts right up , runs fine for about 10 seconds then it goes into misfire mode. I have replaced the crank sensor, pickup coil in dist, 2 sets of wires ,2 sets of plugs, new dist cap , rotor...

Well, aside from the O2 sensors, the throttle position sensor and temp sensor, looks very much like you have a totally new system there.
I assume you got codes for all those item from a system scan?
I suggest that you "ring out" the wiring harness and check every fuse in the engine compartment and in the passenger compartment. If you have continuity and no cross over in the wiring, pretty good chance that the engine computer is bad.
One thing...your fuel pressure seems to be a bit high...I didn't look it up but I'd expect it to be around 35psi to possibly 40? Do the plugs come out clean or black?

97 dodge ram no spark

then i would replace whats called the hall effect sensor its that black plastic plate you see when you take dist cap off. just pull rotor and lift up the sensor.dist cap is what holds it on.also under the sensor will be a stamped sheet metal piece that looks like the top of a castle wall. make sure its not loose on the shaft.if it is then new dist will be needed

After I drive my jeep some, if it is somewhat warm or not cold weather, my jeep has a hard time starting. It may crank but run a little ways and cut off going down the road.I have had the coil, plugs, plug...

if it shuts off after running for a while and will not restart for about 10 min,a bad crank sensor will cause this. abad crank sensor will make car shut off and not restart for about 10 min. put a scanner on to make sure. a check engine light does not allways come on. if you do not have a scanner, any auto parts store will scan it for free.

Replace the spark plugs and wires along with a distributor cap and rotor. Be careful to leave the old wires and plug wires connected to dist.cap, just remove dist. cap from the distributor and lay aside with plug wires on it then install rotor then new cap and proceed to replace each wire for cap and spark plug one at a time so you don't mix up the spark plug wire firing order. Cap laying to the side is used for reference purpose.

Engines don't jump time when they are not running.

Rotor will point to number 1 plug wire with every other rotation of the crank.

Get an auto repair manual to confirm you have plug wires in right order on distributor cap.

Also suggest finding Factory Service Manuals at library to get troubleshooting charts and diagnostics.
