toyota pickup no start
So over the past couple months ive been working on my 1987 4wd carb toyota pickup. I have rebuilt the engine replaced the starter, clutch, battery wires, and alternator. Then two days ago my alternator went out again third one this year. I replace it runs fine till yesterday m engine cut out when i was slowing down so i pop the clutch and it starts back up and runs fine. This morning it starts and i drive to work less than three miles all is good till i park then it stalls didn't have time to work on it till after work. When i got off work i checked my grounds starter wires fuses all the usual stuff but it just spins slowly then clicks tried jumping it but no luck. If anyone has some ideas it would be really appreciated.
thanks
