Hi,

If the issue happens when the engine is warm, the first thing I think of is a possible faulty crankshaft position sensor. When they start to fail, they are adversely affected by heat. When they cool off, they work again.

Do me a favor. Take a look through this link and let me know if it seems to mirror what you experienced.

Next, I need you to scan the computer to see if there are diagnostic trouble codes that may help. This vehicle has an OBD1 system and doesn't require a scan tool to check for codes. All you need is a short jumper wire or even a paper clip.

Here is a link that explains how it's done:

If possible, perform the test above and let me know the results.

Take care,

Joe
