1984 Nissan Datsun 720 King cab 4x4

My engine stalls regularly. What's the fix?
There seems to be two types of stalling.

Type 1: In the last two weeks I've stalled 5 times. These 5 times have all been in parking lots and after the truck has previously run at least 15 min. I start to take my foot off the clutch (stopsign, reversing, etc) and the truck stalls. When I turn the key, it goes tttttt and either no Vroom, or the vroom chokes out after 2 sec. Continued tries = definitely no Vroom. After 20 minutes to an hour it will start as normal. WHAT's GOING ON! ?

Type 2: (happened intermittently for the last year but hasn't happened in the last 2 weeks) While driving, the gas pedal stops engaging, Then the engine then cuts out. Truck coasts to stop and will restart within a couple minutes. Might (or might not) keep stalling. Sometimes you can put it in 2nd gear and buy enough time for the gas pedal to reengage.

Recent work done: new fuel filter, new alternator, plugs and wires, rotor and rotorcap, battery (1 yr), battery terminals

Thanks in advance for your suggestions.

 

My guess is the coil, what you are experiencing is a sign of deteriorating ignition coil pack.
