Hello!

It sounds like you could have a leaky fuel pressure regulator or low fuel pressure. I would recommend to start by checking fuel pressure when this happens and be sure that the fuel pressure does not fall when the key is turned off.

Also, be sure the coolant temp sensor is within specs. IF you need the testing and inspection, let me know

Remove air cleaner assembly from Throttle Body Fuel Injection (TBI) unit (one nut, one bolt, PCV hose, Intake Air Temperature (IAT) sensor connector.
Disconnect one clamp and fuel feed hose from throttle body. Use a shop towel to catch any remaining fuel that may leak.
Install a fuel pressure tester. between fuel feed hose and throttle body. Clamp securely to ensure that no leaks occur.
Install air cleaner assembly to TBI unit (one bolt, one nut, PCV hose, and IAT sensor connector).
Start engine and idle at normal operating temperature.
Check fuel pressure as follows:
Idling 90-140 kPa (13-20 psi) .
Engine not running, ignition switch in the "ON" position 160-210 kPa (23-30 psi) .
Within one minute with engine not running, ignition switch in the "ON" position pressure should hold at about 90 kPa (13 psi) .
If pressure is not within specification, refer to the "Powertrain On-Board Diagnostic (OBD) System Check."

Relieve fuel pressure.
Remove air cleaner assembly from Throttle Body Fuel Injection (TBI) unit (one nut, one bolt, PCV hose, Intake Air Temperature (IAT) sensor connector.
Remove.

Use a shop towel to catch any remaining fuel that may leak.
Connect fuel feed hose to throttle body; secure with one clamp.
Install air cleaner assembly to TBI unit (one bolt, one nut, PCV hose, and IAT sensor connector).
PCV hose, IAT sensor connector and air cleaner to TBI unit; secure with one bolt and nut. Tighten ACL bracket bolt to 10 Nm (7.5 ft lb) .
Reconnect negative (-) battery cable.
Start engine and check for fuel leaks.

SOunds good!

I hope this helps. You can always accept my answer now, and repost back again later on if you have any more questions. If you want to discuss it some more just hit "reply", it's free to do so otherwise don't forget to hit "accept" and leave positive feedback if you found my answer helpful.
