Usually, a Jeep's engine stalls in idle mode because of a battery power fault or because there is no gas. However, it is common for any car to stall when it has not been running for a period of time and the engine is cold.
Had a Jeep in the shop here with that problem last week and it turned out to be low fuel pressure. Try running a fuel pressure test. The Jeep would idle ok but when you tried to accelerate the engine would stall.
Having the speedometer jump and the engine stall in the 1994 Jeep Grand Cherokee Laredo could be a problem with the idle and the transmission. The transmission slipping can cause the speedometer to jump.
