    There are a couple of problems that could cause this problem and the first thing you should do is have the engine control system tested. You need to find out what codes are being set, if they are engine or transmission related. From what you described there should be code stored in the memory of the engine control module. If not then it should be tested when the gear light is not working,( that is when the fault is occurring). You could have a wiring short that is intermittent or the transmission harness pinched or damaged.The manual lever position sensor,( it senses what gear you have selected) may be bad and causing improper gear selection in first gear. A bad speedometer can cause stalling too. It can send the incorrect speed signal to the engine control module and this causes the engine control module to cut the injector signal. I recommend you find someone that is good at diagnostics and have them check this vehicle, it will save you time and probably money too.
