The only thing that it would most likely be (if not the ignition module, the fuel pump, a faulty fuel pump relay if applicable, or a faulty ignition coil pack but only if one coil pack is used, and if more than one coil pack they would all have to be faulty to shut down the engine) is the ECM/ECC, especially since the vehicle shuts down about every 10 minutes, and that is the classical sign of over-heating electronics that act almost normal until the electrical componet becomes too hot and then begins to malfunction.
(Engine Control Module) or ECC
(Engine Control Computer) for those vehicles were not manufactured very well and were prone to failure, and that is why you can purchase a re-manufactured one for only $85.00-$89.00, and the re-manufactured one will not have the stock defects.
If you do purchase an ECM/ECC and if it has a PROM chip (Programable Removable On-board
Memory) that must be installed from your old ECM/ECC be very careful when removing and installing the PROM, and the plastic retainers on either end of the PROM will push back away from the PROM and lift the PROM out of the connector on the circuit board. When installing the PROM be sure that the retainers are pushed
back and that when the PROM is pushed down into the connector that the retainers lock in the PROM. Not all vehicles will have a PROM and be very careful with the PROM if you do have one to remove and install because it can easily be damaged, and if it is a necessary procedure to change the PROM, then the ECM/ECC that you purchased should come with a detailed diagram and procedure for you to follow so that the PROM is properly installed into the ECM/ECC.
Here are two links that show the price of the ECM/ECC from a major auto part store depending on if the vehicle has a 2.5 liter 4 cylinder engine, or a 3.3 liter V-6 engine.
