88 yj dies when it gets warm

i have a 88 yj and after it gets warm (3 - 5 miles) it dies and it will not start for hours later. it acts like it is not getting any fuel. i put a new filter and pump on it replaced the carb with a webber, tune up new dist., coil wires etc..droped gas tank cleaned it put filter in tank. and it still dies.

Simple test.....loosen the gas cap and see if it still happens......could be pulling a vacuum.

If you have a 4.2 you may have a bad Ignition Control Module. You'll initially get spark but when it warms up you'll lose it.
