Cranks but won't start

2000 Grand Cherokee Laredo 4.0L

After shopping, Jeep would not start. Cranks good but won't fire. After trying 5 minutes, it fired. Driving a few days later, Jeep died going down the road, seconds later it started by itself and I kept going until 5 miles later it died. Pulled off the road and tried to start it for a few minutes with no luck. About 10 minutes later I cranked it and it fired.
Anyone experience this situation?
Possible solutions?
Thanks

Maybe the fuel pump. Im not exactly sure how to test the pressure, try searching. Also, what Year/Motor do you have?
